Pancreatic Cancer Signs You Might Overlook

19. Bloating Persistent abdominal bloating and distension are symptoms that can develop when pancreatic cancer affects normal digestive processes. Tumors may obstruct the flow of digestive… Diana Yasinskaya - August 22, 2025

According to the American Cancer Society, pancreatic cancer accounts for about 3% of all cancers in the United States but causes around 7% of all cancer deaths. The pancreas, a vital organ in the digestive system, helps regulate blood sugar and aids in food digestion. Unfortunately, the early signs of pancreatic cancer are often subtle and nonspecific, making timely diagnosis difficult. This lack of obvious symptoms frequently results in detection at advanced stages, contributing to its high mortality rate.

1. Unexplained Weight Loss

Unintentional weight loss is a prominent yet often overlooked sign of pancreatic cancer. As tumors develop in the pancreas, they can interfere with the organ’s ability to secrete enzymes essential for digesting and absorbing nutrients from food. This disruption leads to malabsorption, making it difficult for the body to maintain a healthy weight despite normal eating habits. Over time, the body begins to break down fat and muscle for energy, resulting in noticeable and unexplained weight loss.

For example, a patient may notice that their clothes fit more loosely or that they’ve lost 10 pounds or more within a few months without increasing exercise or dieting. Such changes can be subtle at first and are often attributed to stress or aging, but persistent weight loss should not be ignored. According to the American Society of Clinical Oncology, unintentional weight loss, especially when accompanied by other symptoms like fatigue or digestive issues, warrants prompt medical evaluation. If you experience significant, unexplained weight loss—typically more than 5% of your body weight over six to twelve months—it’s important to consult a healthcare professional for further assessment.

2. Jaundice

2. Jaundice
Yellowing of skin and eyes due to bile duct obstruction, an early sign of pancreatic cancer.

Jaundice, characterized by a yellowing of the skin and the whites of the eyes, is a classic symptom of pancreatic cancer that is often overlooked in its early stages. Tumors in the pancreas, particularly those located near the head of the organ, can press on or block the common bile duct. This obstruction prevents bile—a substance produced by the liver to aid digestion—from draining into the intestines, causing it to accumulate in the bloodstream and resulting in the yellow discoloration seen in jaundice.

While jaundice can also result from other medical conditions such as hepatitis, gallstones, or liver disease, the onset of painless jaundice is especially concerning for pancreatic cancer. Unlike jaundice caused by infections, which may be accompanied by fever or abdominal pain, jaundice from pancreatic cancer often occurs without significant discomfort. According to the Cancer Research UK, any new or unexplained yellowing of the skin or eyes should prompt immediate medical attention. If you notice jaundice—especially when paired with other symptoms such as dark urine or pale stools—it’s important to seek evaluation from a healthcare provider to identify the underlying cause and ensure timely treatment.

3. New-Onset Diabetes

Sudden development of diabetes, particularly in individuals with no prior risk factors, can be an early indicator of pancreatic cancer. The pancreas plays a crucial role in regulating blood sugar by producing insulin. When a tumor forms, it can disrupt the function of insulin-producing cells, leading to elevated blood glucose levels. This may manifest as new-onset diabetes, often without the typical risk factors such as obesity or a family history of diabetes.

For instance, a person in their 50s who maintains a healthy lifestyle and weight might suddenly develop symptoms like increased thirst, frequent urination, or unexpected fatigue. According to the Pancreatic Cancer UK, research shows that up to 1 in 10 people with pancreatic cancer are first diagnosed with diabetes. While most cases of diabetes are not caused by cancer, new or rapidly worsening diabetes in adults over 50, especially if accompanied by weight loss or digestive issues, should raise concern. In such cases, it is advisable to discuss the possibility of pancreatic screening with a healthcare provider to rule out underlying malignancy and ensure prompt intervention if necessary.

4. Abdominal Pain

Abdominal pain is a frequently overlooked symptom of pancreatic cancer, particularly in its early stages. The pain associated with pancreatic cancer often develops gradually and is typically located in the upper abdomen, just below the ribs. It may be persistent or come and go, and is distinctive because it often radiates to the back. This back pain occurs because the pancreas is situated deep within the abdomen, close to the spine. The discomfort may worsen after eating or when lying down and can sometimes be relieved by leaning forward.

Unlike the sharp, sudden pain of conditions such as gallstones or the cramping of gastrointestinal infections, pain from pancreatic cancer tends to be dull, deep, and persistent. According to the NHS, people may also experience bloating or a feeling of fullness. It’s important to pay attention to pain that is new, ongoing, or gradually intensifying, especially if it radiates to the back or is accompanied by other symptoms like weight loss or jaundice. Persistent upper abdominal discomfort, particularly in adults over the age of 50, should prompt consultation with a healthcare professional for further evaluation and diagnosis.

5. Loss of Appetite

5. Loss of Appetite

Loss of appetite, or anorexia, is a subtle yet significant symptom associated with pancreatic cancer. Tumors in the pancreas can disrupt normal digestion by interfering with enzyme production, leading to a sensation of early fullness and decreased interest in food. In addition, cancer-related inflammation and metabolic changes can alter the body’s hunger signals, further suppressing appetite. Over time, these factors combine to make eating less enjoyable or even uncomfortable, causing individuals to unintentionally skip meals or eat much less than usual.

Unlike the temporary loss of appetite that commonly accompanies stress, minor illnesses, or changes in routine, the appetite change linked to pancreatic cancer is persistent and often accompanies other symptoms such as weight loss, nausea, or abdominal discomfort. According to the Mayo Clinic, ongoing lack of interest in food that lasts for more than a couple of weeks, especially in adults with no recent illness or obvious cause, should not be ignored. If you or someone you know experiences a prolonged reduction in appetite along with other warning signs, it’s important to seek medical advice promptly to rule out serious underlying conditions.

6. Nausea and Vomiting

6. Nausea and Vomiting

Nausea and vomiting are symptoms that can occur when a pancreatic tumor grows large enough to partially block the digestive tract, especially the duodenum—the first part of the small intestine. This obstruction prevents food and digestive fluids from moving normally through the stomach and intestines, leading to persistent nausea and sometimes forceful vomiting after meals. In addition, impaired pancreatic enzyme production can result in poor digestion, further contributing to these symptoms.

For example, someone might notice that they feel queasy or bloated after eating, and may vomit undigested food hours after a meal. These symptoms are easy to dismiss as food poisoning or a stomach virus, but when nausea and vomiting linger for more than a few days and do not improve with rest or hydration, it could indicate a more serious problem like pancreatic cancer. The American Cancer Society recommends that persistent gastrointestinal symptoms, especially in adults over 50 or those with other risk factors, should always be evaluated by a healthcare provider. Timely medical attention can help identify the root cause and prevent complications related to prolonged vomiting and poor nutrient intake.

7. Light-Colored or Greasy Stools

One often-missed sign of pancreatic cancer is the appearance of pale, light-colored, or greasy stools. This occurs when a tumor blocks the bile duct or prevents the pancreas from releasing enough digestive enzymes. Bile gives stools their typical brown color; when its flow is interrupted, stools may appear yellowish, gray, or clay-colored. Similarly, inadequate pancreatic enzymes mean fats from food aren’t properly digested, resulting in stools that are oily, float, and may be difficult to flush or have a foul odor.

While occasional changes in stool color or consistency can be caused by dietary factors—such as eating high-fat foods or certain medications—persistent light or greasy stools are more concerning. According to the Cancer Treatment Centers of America, these changes often accompany other digestive symptoms and should not be ignored, especially if they last for more than a week. If you notice ongoing pale, oily, or hard-to-flush stools, particularly when associated with unexplained weight loss or jaundice, it is important to seek medical advice. Early evaluation can help detect underlying pancreatic issues before they progress to more advanced disease.

8. Dark Urine

8. Dark Urine

Dark urine is another subtle symptom that can be associated with pancreatic cancer, often resulting from a buildup of bilirubin in the bloodstream. When a pancreatic tumor blocks the bile duct, bilirubin—a yellow pigment formed by the breakdown of red blood cells—cannot be properly excreted into the intestines. As a result, it accumulates in the body and is filtered out by the kidneys, giving urine a noticeably darker, tea- or cola-like color.

While urine color can fluctuate due to dehydration (resulting in concentrated, darker urine), pancreatic cancer-related darkening is typically persistent and does not improve with increased fluid intake. According to the Memorial Sloan Kettering Cancer Center, dark urine often occurs alongside other signs of jaundice, such as yellowing of the skin or eyes and pale stools. If you observe that your urine remains dark despite adequate hydration, or if it appears in conjunction with other unexplained symptoms like fatigue or abdominal discomfort, it’s important to consult a healthcare provider promptly. Persistent changes in urine color may signal a bile duct obstruction or other serious underlying condition needing timely attention.

9. Fatigue

9. Fatigue
Persistent fatigue in pancreatic cancer results from inflammation, nutrient malabsorption, and disrupted energy metaboli…

Fatigue is a common but frequently underestimated symptom of pancreatic cancer. Chronic inflammation caused by the tumor can release cytokines—molecules that disrupt normal cellular function and sap energy levels. Additionally, as the pancreas becomes less effective at producing enzymes, the body absorbs fewer nutrients from food, leading to malnutrition and persistent tiredness. This means that even with adequate sleep, individuals may still feel drained and struggle to complete daily activities.

For example, someone who previously enjoyed regular walks or social activities may suddenly find themselves too exhausted to participate, needing frequent rest breaks, or falling behind at work. Unlike temporary fatigue due to a poor night’s sleep or a busy week, cancer-related fatigue is ongoing and doesn’t improve with rest. According to the Pancreatic Cancer Action Network, fatigue that persists for several weeks and interferes with daily functioning should be evaluated, especially if it is accompanied by other symptoms like weight loss or digestive changes. Recognizing and acting on persistent, unexplained fatigue can lead to earlier diagnosis and improved outcomes for those with pancreatic cancer or other serious conditions.

10. Itchy Skin

Itchy skin, or pruritus, is a lesser-known symptom of pancreatic cancer but can occur when a tumor blocks the bile duct and causes bile to build up in the bloodstream. The accumulation of bile salts beneath the skin triggers intense itching, which can affect the whole body or be more pronounced on the hands and feet. This symptom often appears alongside jaundice, as rising bilirubin levels are responsible for both the yellowing of the skin and the associated itchiness.

Unlike mild, temporary itching caused by dry weather, allergic reactions, or insect bites, the itching related to pancreatic cancer is often persistent, severe, and not easily relieved with topical creams or moisturizers. According to the American Cancer Society, unexplained, ongoing itching—especially when accompanied by other signs like dark urine, pale stools, or jaundice—should prompt a medical evaluation. If you experience continuous or worsening skin itchiness that does not resolve with standard remedies and is associated with additional concerning symptoms, it is important to seek advice from a healthcare professional to investigate potential underlying causes such as pancreatic or liver conditions.

11. Back Pain

Persistent back pain is another symptom that can be linked to pancreatic cancer, though it is often mistaken for more common musculoskeletal issues. As a pancreatic tumor grows, it may extend toward the back of the abdomen, pressing on surrounding nerves or invading nearby tissues. This pressure can produce a constant, deep ache in the mid-to-lower back, sometimes described as a dull or gnawing pain. Unlike typical back pain caused by muscle strain—which usually improves with rest, position changes, or over-the-counter pain relief—pain related to pancreatic cancer tends to linger and may worsen when lying down or after eating.

For example, someone might notice that their back pain does not respond to usual treatments and seems unrelated to physical activity or injury. According to the Cancer Treatment Centers of America, persistent back pain that is not relieved by rest or is associated with other symptoms such as unexplained weight loss, jaundice, or digestive problems warrants further investigation. If you experience ongoing, unexplained back pain—especially if it is accompanied by other warning signs—it is important to consult a healthcare provider to rule out underlying causes, including pancreatic or other abdominal cancers.

12. Blood Clots

Pancreatic cancer can create a hypercoagulable state, meaning it increases the risk of blood clots forming in veins—also known as deep vein thrombosis (DVT). Tumors release substances that interfere with normal blood clotting mechanisms, making clots more likely even in the absence of typical risk factors like immobility or recent surgery. In some instances, the sudden appearance of a blood clot is the first noticeable sign of pancreatic cancer, occurring before any digestive or systemic symptoms appear.

For example, a person might experience unexplained swelling, redness, or pain in the lower leg or arm, which can signal a DVT. According to the Mayo Clinic, blood clots in people without obvious risk factors should always prompt further investigation for underlying causes, such as cancer. Because blood clots can lead to life-threatening complications like pulmonary embolism, any new, unexplained symptoms of clotting—such as sudden swelling, pain, redness, or warmth in a limb—require urgent medical evaluation. Early detection and treatment of blood clots can prevent serious complications and may also help uncover hidden pancreatic or other types of cancer.

13. Depression or Mood Changes

Emerging research has found a notable association between pancreatic cancer and the sudden onset or worsening of depression and mood changes, often preceding any physical symptoms. Scientists believe this connection may be due to the release of certain inflammatory molecules by the tumor, which can affect brain chemistry and emotional well-being. In some cases, individuals develop significant depression, anxiety, or irritability—sometimes months before a cancer diagnosis is made.

Unlike mood changes triggered by external stressors or longstanding mental health conditions, depression related to pancreatic cancer is often abrupt and may not be explained by life circumstances. According to the National Cancer Institute, new or rapidly worsening mood disturbances, especially in individuals without a prior history of mental illness, warrant careful medical assessment. If you or someone you know experiences unexplained sadness, withdrawal, loss of interest, or significant mood swings—particularly when accompanied by physical symptoms like fatigue or weight loss—it is important to seek both mental health and medical evaluation. Early recognition of these psychological symptoms can lead to timely investigation and potentially earlier detection of pancreatic or other serious illnesses.

14. Indigestion or Heartburn

14. Indigestion or Heartburn

Persistent indigestion or heartburn can sometimes be a subtle indicator of pancreatic cancer. As a tumor grows, it may compress nearby organs such as the stomach or duodenum, or interfere with pancreatic enzyme production, resulting in incomplete digestion of food. This disruption can cause ongoing discomfort, bloating, or a burning sensation in the chest or upper abdomen, often mistaken for common gastrointestinal issues like acid reflux or gastritis.

Unlike typical heartburn, which is usually relieved by over-the-counter antacids and associated with specific foods or activities, the symptoms linked to pancreatic cancer are often more persistent and resistant to standard treatments. According to the NHS, indigestion that lasts for several weeks, occurs without obvious dietary triggers, or is accompanied by other warning signs—such as unintended weight loss, jaundice, or upper abdominal pain—should be evaluated by a healthcare provider. If you notice that your heartburn or indigestion is ongoing, worsening, or occurs alongside other unusual symptoms, do not ignore it. Early assessment can help identify the underlying cause and ensure timely treatment if a serious condition is present.

15. Difficulty Swallowing

15. Difficulty Swallowing

Although difficulty swallowing, or dysphagia, is less commonly associated with pancreatic cancer, it can occur when a tumor is situated near the duodenum or upper part of the small intestine, or if the cancer spreads to nearby tissues. In these rare cases, the tumor may partially obstruct the passage of food from the stomach into the intestines, resulting in a sensation of food sticking, choking, or discomfort when swallowing solids or liquids.

For example, while most episodes of swallowing difficulty are caused by acid reflux, throat infections, or benign conditions like esophageal spasms, persistent or worsening dysphagia—especially in adults with no previous history—can signal a more serious underlying issue. According to American Cancer Society, difficulty swallowing that lasts beyond a few days, is accompanied by unintentional weight loss, vomiting, or other digestive symptoms, should not be ignored. If you or someone you know experiences ongoing trouble swallowing, particularly in conjunction with other warning signs, a thorough evaluation by a healthcare provider is recommended to rule out structural or malignant causes and ensure timely diagnosis and management.

16. Enlarged Gallbladder

16. Enlarged Gallbladder

An enlarged gallbladder can sometimes be a subtle sign of pancreatic cancer, especially when a tumor blocks the common bile duct. This blockage causes bile to back up, leading to swelling and distension of the gallbladder. Often, this enlargement is not noticeable to the patient and may only be detected during a physical exam or observed incidentally during imaging studies such as an ultrasound or CT scan performed for unrelated reasons.

Unlike gallstones, which frequently cause sudden, sharp pain (biliary colic), fever, and sometimes infection (cholecystitis), an enlarged gallbladder due to pancreatic cancer is typically painless. According to Cleveland Clinic, the presence of a non-tender, palpable gallbladder in a jaundiced patient (Courvoisier’s sign) is a classic indicator suggesting malignancy rather than gallstones. If imaging reveals an enlarged gallbladder in conjunction with jaundice or other pancreatic cancer symptoms, it warrants prompt further investigation. Early identification of this sign can help distinguish between benign and malignant causes of biliary obstruction and can be critical for guiding appropriate treatment and improving patient outcomes.

17. Frequent Belching

Frequent belching, or burping, can sometimes be an overlooked symptom of pancreatic cancer, especially when it becomes persistent and unexplained. As a pancreatic tumor disrupts normal digestive processes by interfering with enzyme production or causing partial obstruction in the upper digestive tract, gas can accumulate, leading to ongoing belching. This symptom is often subtle and easily dismissed as dietary or lifestyle related, such as swallowing air while eating or drinking carbonated beverages.

In most cases, belching is harmless and results from common factors like eating too quickly, consuming fizzy drinks, or indigestion. However, when belching becomes unusually persistent, occurs daily without clear triggers, or is accompanied by other symptoms such as unexplained weight loss, early satiety, or abdominal discomfort, it may warrant further evaluation. According to Cancer Treatment Centers of America, ongoing digestive symptoms should not be ignored, especially in adults over 50 or those with additional risk factors. If you notice a significant change in your belching habits that lasts for weeks and does not respond to simple dietary adjustments, it’s advisable to consult a healthcare provider for a thorough assessment to rule out serious underlying conditions.

18. Hiccups

Chronic or persistent hiccups can be an unusual and easily overlooked symptom of pancreatic cancer. The pancreas sits deep within the abdomen, close to the diaphragm—the muscle responsible for breathing. When a tumor grows, it can irritate or put pressure on the diaphragm or the nerves that control it, leading to ongoing hiccups that may last for hours or even days. This irritation causes involuntary contractions, resulting in persistent or recurring bouts of hiccups.

Most hiccups are harmless, short-lived, and commonly triggered by eating too quickly, consuming spicy foods, or drinking carbonated beverages. These benign episodes typically resolve on their own and do not indicate any serious underlying condition. However, according to Cancer.Net, persistent hiccups lasting more than 48 hours or occurring alongside other symptoms such as abdominal pain, jaundice, or unexplained weight loss should raise concern. If you experience hiccups that are unusually frequent, severe, or do not resolve with typical remedies, it is important to consult a healthcare provider. Persistent hiccups may be a subtle signal of irritation or disease affecting the abdomen or nervous system, including pancreatic cancer.

19. Bloating

19. Bloating
Pancreatic cancer disrupts digestion, causing persistent bloating, abdominal distension, and discomfort after eating.

Persistent abdominal bloating and distension are symptoms that can develop when pancreatic cancer affects normal digestive processes. Tumors may obstruct the flow of digestive enzymes or partially block the intestines, causing food and gas to build up in the stomach and bowel. This can result in a constant feeling of fullness, visible swelling, and discomfort, even after eating small amounts of food. In addition, impaired fat digestion leads to increased gas production, further contributing to bloating.

While occasional bloating is common and usually related to overeating, hormonal fluctuations, or dietary factors such as consuming beans or carbonated drinks, the bloating associated with pancreatic cancer is more persistent and often unrelated to recent meals. According to the Cancer Council Australia, ongoing bloating that lasts for several weeks, especially when accompanied by other symptoms like weight loss, appetite changes, or jaundice, should not be ignored. If you notice that bloating is frequent, does not resolve with dietary changes, or is associated with additional warning signs, it is important to consult a healthcare provider for further evaluation to rule out serious underlying causes, including pancreatic cancer.

20. Fever

Low-grade fever can sometimes be an overlooked symptom of pancreatic cancer, particularly when it is persistent or unexplained. Tumor growth may trigger chronic inflammation within the pancreas or surrounding tissues, leading to a slight, ongoing elevation in body temperature. In some cases, blockage of the bile duct by the tumor can also result in infection (cholangitis), which may cause more pronounced fevers and chills.

Unlike the high fevers that typically accompany viral infections or flu—which usually resolve within a few days and are associated with sore throat or respiratory symptoms—the fever linked to pancreatic cancer is often mild, recurrent, and may be accompanied by fatigue, night sweats, or general malaise. As noted by the Cancer Treatment Centers of America, persistent fever without an obvious cause, especially when paired with other concerning symptoms such as jaundice, unexplained weight loss, or abdominal pain, should prompt a thorough medical evaluation. Early investigation can help identify underlying inflammation, infection, or malignancy, ensuring appropriate intervention and improved outcomes.

21. Night Sweats

21. Night Sweats

Night sweats—episodes of excessive sweating during sleep—can occasionally be a subtle symptom of pancreatic cancer. The disease can trigger systemic inflammation, releasing cytokines and other chemicals that disrupt the body’s normal temperature regulation. This inflammatory response may cause the body to sweat profusely at night, often soaking through sleepwear and sheets, even in a cool room. In some cases, night sweats may also be related to low-grade fever or infection associated with bile duct obstruction.

While night sweats are commonly linked to benign causes such as menopause, stress, certain medications, or infections like the flu, the pattern seen with pancreatic cancer is typically persistent and unexplained. According to the Cancer Research UK, ongoing night sweats, especially when accompanied by other symptoms such as unexplained weight loss, fever, or fatigue, should raise concern. If you experience frequent, drenching night sweats that are not related to environmental factors or known health conditions, it is important to seek medical advice. Persistent night sweats may be an early sign of an underlying malignancy or systemic illness requiring prompt evaluation.

22. Pale Skin

22. Pale Skin

Pale skin, or pallor, can develop in individuals with pancreatic cancer due to two primary mechanisms: anemia and impaired bile flow. Anemia may arise from chronic disease or nutritional deficiencies caused by poor absorption of nutrients, leading to a reduced number of red blood cells and less oxygen delivered to tissues. Additionally, when a tumor blocks the bile duct, the skin may lose its healthy pink tone and appear unusually pale, sometimes in combination with yellowing (jaundice).

While paleness can result from temporary factors such as fatigue, cold exposure, or mild illness, persistent or progressive skin paleness—particularly when it is not related to these common causes—should prompt closer observation. According to the Cancer Council Australia, subtle skin changes, especially when accompanied by symptoms like fatigue, shortness of breath, or jaundice, may signal an underlying issue such as pancreatic cancer. If you notice that your skin or the inside of your eyelids appears paler than usual for more than a couple of weeks, or if it occurs alongside other concerning symptoms, it is advisable to consult a healthcare provider for further evaluation and blood tests.

23. Swollen Lymph Nodes

23. Swollen Lymph Nodes

Swollen lymph nodes can occasionally be a sign that pancreatic cancer has spread beyond the pancreas itself. Lymph nodes act as filters for the immune system, and when cancer cells travel to these nodes, they may become enlarged and sometimes tender. This swelling is usually noted in lymph nodes near the collarbone, armpits, or neck, although it can also occur deeper in the abdomen, where it may only be detected through imaging studies.

Most often, lymph node swelling is caused by infections such as colds, sore throats, or minor skin irritations and is typically accompanied by pain, redness, or warmth. These benign causes usually resolve within a few weeks. In contrast, lymph node enlargement from cancer is often painless and persistent, gradually increasing in size over time. According to the American Cancer Society, unexplained, persistent lymph node swelling—especially when not associated with infection or accompanied by other symptoms like weight loss or jaundice—should prompt further investigation by a healthcare professional. Early identification can help guide appropriate treatment strategies and improve long-term outcomes.

24. Easy Bruising

24. Easy Bruising

Easy bruising can be an overlooked sign of advanced pancreatic cancer, particularly when the disease affects liver function. As the tumor spreads to or compresses the liver or major bile ducts, the production of essential proteins involved in blood clotting—such as clotting factors and platelets—can decrease. This impairment means that even minor bumps or injuries may result in large, dark bruises that take an unusually long time to heal.

For example, someone might notice bruises appearing on their arms or legs without recalling any significant trauma, or find that small cuts bleed longer than usual. Unlike the occasional bruise from everyday activities, repeated or unexplained bruising deserves closer attention. According to the Cancer Treatment Centers of America, easy bruising or bleeding may indicate liver dysfunction or blood clotting abnormalities, which can be associated with late-stage pancreatic cancer. If you experience frequent or severe bruising, especially in conjunction with other symptoms such as jaundice, fatigue, or abdominal discomfort, it’s important to consult a healthcare provider promptly. Early intervention can help manage complications and improve the quality of life for those affected.

25. Slow-Healing Wounds

Slow-healing wounds can be an indirect sign of pancreatic cancer, especially as the disease impairs the body’s ability to absorb nutrients and weakens the immune system. When the pancreas is unable to produce sufficient digestive enzymes, nutrient deficiencies—particularly in proteins, vitamins, and minerals essential for tissue repair—become more common. This compromised nutritional status, in combination with the immune-suppressing effects of cancer, can delay the healing process for cuts, sores, or abrasions.

For example, someone may notice that a small scrape or minor surgical incision takes several weeks to close, or that wounds are more prone to infection and redness. While slow healing can also be caused by diabetes, vascular disease, or certain medications, persistent delays in recovery should not be ignored. According to the Pancreatic Cancer UK, problems with wound healing, particularly when accompanied by other symptoms like unexplained weight loss, fatigue, or digestive changes, warrant medical attention. If you observe that your wounds are taking longer than usual to heal or are frequently becoming infected, consult a healthcare provider to assess for underlying medical issues, including possible pancreatic dysfunction.

26. Chronic Cough

26. Chronic Cough

Chronic cough is an uncommon but possible symptom of pancreatic cancer, particularly when the tumor is positioned high in the abdomen, close to the diaphragm, or when the cancer has metastasized to the lungs. In these scenarios, the tumor or metastatic lesions may irritate the respiratory tract or diaphragm, triggering a persistent, dry cough that does not resolve with typical treatments. This cough may be accompanied by shortness of breath, chest discomfort, or hoarseness.

Most chronic coughs are caused by respiratory infections, allergies, post-nasal drip, or smoking, and typically improve with over-the-counter remedies or after the underlying cause is treated. However, a cough associated with pancreatic cancer is usually resistant to standard treatments and may persist for weeks or months without a clear explanation. According to the American Society of Clinical Oncology, a new, persistent cough—especially when associated with unexplained weight loss, chest pain, or other systemic symptoms—should prompt evaluation by a healthcare provider. If a cough lingers despite standard care or occurs alongside other warning signs, it is important to seek further assessment to rule out metastatic or advanced disease.

27. Shortness of Breath

27. Shortness of Breath
Shortness of breath in pancreatic cancer may result from blood clots, fluid buildup, or metastasis.

Shortness of breath, or dyspnea, can develop in pancreatic cancer patients due to several mechanisms, including blood clots traveling to the lungs (pulmonary embolism) or fluid buildup in the abdomen or chest from advanced disease. Blood clots are more common in pancreatic cancer because the disease increases the body’s tendency to form clots, which can suddenly block blood flow in the lungs and cause acute breathing difficulties. Additionally, metastatic spread to the lungs or pleura may result in persistent breathlessness.

While shortness of breath is often caused by conditions such as asthma, heart failure, or respiratory infections, the onset of unexplained or rapidly worsening breathlessness in someone with risk factors for or symptoms of pancreatic cancer should not be ignored. According to the American Cancer Society, sudden, severe shortness of breath—especially if accompanied by chest pain, coughing up blood, or fainting—requires immediate emergency care, as it may signal a life-threatening pulmonary embolism. Persistent or progressive breathlessness without an obvious cause should prompt timely medical evaluation to identify and manage underlying complications of pancreatic cancer.

28. Swelling in Legs or Ankles

Swelling in the legs or ankles, also known as peripheral edema, can occur in individuals with pancreatic cancer due to impaired circulation or the development of blood clots. Tumors may compress blood vessels in the abdomen, impeding the normal return of blood from the lower extremities to the heart. Additionally, pancreatic cancer increases the risk of deep vein thrombosis (DVT), where a clot forms in a leg vein, leading to swelling, tenderness, and sometimes redness or warmth in the affected area.

While mild ankle swelling is common after long periods of standing or sitting and can be related to benign causes like minor injuries or salt intake, persistent or sudden swelling—especially if it is one-sided, painful, or associated with shortness of breath—should raise concern. For example, someone might notice their shoes feel tight by midday or see a visible indent left after pressing on the swollen skin. According to the Cancer Treatment Centers of America, ongoing or unexplained leg swelling warrants medical evaluation, as it may indicate an underlying clot or complications from cancer. Early detection is crucial to prevent serious problems such as pulmonary embolism or chronic venous insufficiency.

29. Muscle Weakness

29. Muscle Weakness

Muscle weakness is a symptom that can emerge in individuals with pancreatic cancer due to cancer-related malnutrition or electrolyte imbalances. As the disease impairs the pancreas’s ability to secrete digestive enzymes, the body absorbs fewer nutrients—including proteins, potassium, calcium, and magnesium—that are vital for healthy muscle function. Over time, this nutritional deficiency can lead to muscle wasting and generalized weakness. Additionally, tumors or cancer treatments may disrupt fluid and electrolyte balance, further exacerbating weakness and fatigue.

For example, a person who previously had no trouble climbing stairs or lifting groceries might suddenly struggle with everyday activities or feel their legs “give out” more easily. While mild muscle weakness can result from inactivity, temporary illness, or aging, persistent or rapidly worsening weakness—especially when accompanied by weight loss, appetite changes, or other unexplained symptoms—should prompt medical evaluation. According to the Cancer Council Australia, ongoing or severe muscle weakness may signal advanced disease or complications that require prompt intervention. If you notice a marked decline in your strength or ability to perform routine tasks, consult a healthcare provider for a thorough assessment and appropriate management.

Persistent hiccups—those lasting more than 48 hours—can sometimes be connected to pancreatic cancer, particularly when a tumor irritates the diaphragm or its associated nerves. The pancreas is located near the diaphragm, and as a tumor grows, it can exert pressure on or inflame the phrenic or vagus nerves, which help control diaphragmatic movement. This irritation triggers involuntary contractions, resulting in chronic, hard-to-resolve hiccups.

Most hiccups are brief and harmless, often resolving within minutes or hours after eating quickly, drinking carbonated beverages, or experiencing excitement. However, when hiccups persist for days or occur more frequently without obvious cause, they may signal an underlying health issue. According to the American Society of Clinical Oncology, persistent hiccups—especially when associated with other warning signs like abdominal pain, unexplained weight loss, or digestive changes—should prompt medical attention. Prolonged hiccups can also disrupt sleep and eating, further diminishing quality of life. If you experience hiccups lasting more than 48 hours or that are difficult to control, consult a healthcare provider to investigate potential causes, including abdominal tumors such as pancreatic cancer.

Scurvy-like symptoms can occasionally develop in pancreatic cancer patients due to impaired digestion and nutrient absorption. When the pancreas fails to produce enough enzymes, essential vitamins such as vitamin C may not be absorbed efficiently from the diet, especially if appetite is also reduced. Vitamin C deficiency leads to symptoms reminiscent of scurvy, such as bleeding gums, swollen or loose teeth, easy bruising, and poor wound healing.

Unlike true scurvy, which is rare in developed countries and usually results from a severely deficient diet, these symptoms in the context of pancreatic cancer are part of a broader pattern of malnutrition and may be accompanied by weight loss, fatigue, and other digestive issues. According to the Pancreatic Cancer UK, any signs of vitamin or mineral deficiency—such as unexplained bleeding gums, frequent infections, or new dental issues—should prompt further investigation, particularly when combined with other warning signs of digestive disruption. If you notice symptoms suggestive of vitamin deficiency that do not respond to dietary improvement, it is important to consult a healthcare provider to assess underlying causes and receive appropriate nutritional support.

32. Frequent Infections

Frequent infections can be a sign of advanced pancreatic cancer, as the disease and its associated malnutrition weaken the immune system’s ability to fight off bacteria, viruses, and fungi. Tumors may also disrupt the production of white blood cells, or block the flow of bile, leading to bacterial overgrowth and an increased risk of infections in the digestive tract, lungs, or urinary system. This immune suppression often results in more frequent or severe illnesses, such as repeated colds, urinary tract infections, or even pneumonia.

For instance, someone might find themselves needing antibiotics several times within a short period, or notice that minor infections take longer than usual to resolve. Unlike infections caused by a temporary cold or stress, these recurrent episodes often lack a clear trigger and may be accompanied by other symptoms of systemic illness, such as weight loss or fatigue. According to the Pancreatic Cancer UK, repeated or difficult-to-treat infections, particularly in adults who are otherwise healthy, should prompt a medical assessment. If you experience ongoing or unusually severe infections, consult your healthcare provider for a comprehensive evaluation to rule out immune system compromise or underlying malignancy.

33. Vision Changes

Vision changes are a rare but possible symptom in individuals with pancreatic cancer, often resulting from metabolic disturbances associated with the disease. For example, pancreatic cancer can lead to new-onset or poorly controlled diabetes, which in turn causes fluctuating blood sugar levels that can temporarily blur vision or cause difficulty focusing. In more advanced cases, malnutrition and deficiencies in fat-soluble vitamins (like vitamin A) due to poor pancreatic function may also impact eye health and sight.

While most vision changes are caused by common issues such as aging, eyestrain, or uncorrected refractive errors, persistent or sudden changes—especially when accompanied by other systemic symptoms like fatigue or unexplained weight loss—warrant further investigation. According to the Pancreatic Cancer UK, people with diabetes or pancreatic disorders should be vigilant about any changes in their eyesight, including blurriness, double vision, or difficulty adjusting to light. If you experience ongoing vision disturbances that don’t resolve with rest or a change in lighting, or if they occur alongside other warning signs, it’s important to consult an eye specialist and inform your healthcare provider to rule out underlying metabolic or systemic issues.

34. Difficulty Concentrating

Difficulty concentrating, often described as “brain fog,” can develop in people with pancreatic cancer due to the combined effects of chronic illness, inflammation, and malnutrition. When the body is deprived of essential nutrients—particularly glucose and B vitamins required for brain function—mental clarity and focus suffer. Chronic pain, sleep disturbances, and the emotional stress of managing undiagnosed symptoms can further impair cognitive performance.

For example, someone who was previously sharp at work or adept at managing daily tasks might begin to forget appointments, struggle to follow conversations, or have trouble making decisions. While occasional lapses in concentration are common during periods of stress or fatigue, persistent and unexplained cognitive changes—especially in adults who have not experienced these issues before—should not be dismissed. According to the Pancreatic Cancer UK, ongoing difficulty with memory, focus, or decision-making that interferes with daily life may signal underlying systemic problems, including cancer-related metabolic or nutritional deficiencies. If you or a loved one notice persistent “brain fog” or mental sluggishness, particularly alongside other symptoms like fatigue or weight loss, consult a healthcare provider for comprehensive assessment and support.

35. Taste Changes

Altered taste perception is a subtle symptom that can occur in individuals with pancreatic cancer. Tumor-related changes in metabolism, chronic inflammation, or impaired digestive enzyme production may affect the way foods taste or smell. People might notice that foods once enjoyed now taste bland, bitter, metallic, or unpleasant, leading to a shift in food preferences and decreased appetite. This phenomenon, known as dysgeusia, can further exacerbate malnutrition and weight loss.

Normal taste fluctuations are common and often related to minor illnesses like colds, seasonal allergies, or certain medications, and typically resolve in a few days. However, persistent or progressive taste changes without an obvious cause—especially when accompanied by other symptoms such as loss of appetite, weight loss, or digestive discomfort—should be taken seriously. According to the Cancer Treatment Centers of America, ongoing taste disturbances may be an early indication of underlying illness, including cancer. If you experience a continuous change in taste that affects your ability to enjoy or consume food for more than two weeks, consult a healthcare professional for evaluation and nutritional guidance, as early intervention can help address both the symptom and its root cause.

36. Hoarseness

Persistent hoarseness can sometimes be a subtle sign of pancreatic cancer, particularly when the tumor affects nerves or causes chronic acid reflux. As the tumor grows, it may press on or irritate the recurrent laryngeal nerve, which controls the vocal cords, leading to changes in voice quality such as hoarseness, raspiness, or a weak voice. In other cases, pancreatic cancer can induce acid reflux by disrupting normal digestive processes, and repeated exposure of stomach acid to the vocal cords can also cause chronic hoarseness.

Most cases of hoarseness are related to benign conditions, like upper respiratory infections, allergies, excessive voice use, or temporary laryngitis, and typically resolve within a week or two. According to the Cancer Treatment Centers of America, hoarseness that lasts longer than three weeks, is accompanied by difficulty swallowing, persistent cough, or other concerning symptoms, should be evaluated by a healthcare provider. If you notice ongoing changes in your voice with no improvement, especially when accompanied by additional digestive or systemic symptoms, it is important to seek medical advice for further assessment and to rule out serious underlying causes, including nerve involvement from cancer.

37. Frequent Urination

37. Frequent Urination
Frequent urination and increased thirst may signal metabolic changes linked to pancreatic cancer.

Frequent urination, or polyuria, can be an indirect symptom of pancreatic cancer, commonly arising from new-onset diabetes or significant metabolic changes. As pancreatic tumors disrupt insulin production, blood sugar levels can rise, and the kidneys work harder to eliminate excess glucose from the bloodstream. This process increases urine output, leading to more frequent trips to the bathroom, particularly at night. Additionally, dehydration from this fluid loss can cause increased thirst, creating a cycle of drinking and urinating more often.

For example, someone may notice they are waking up several times at night to urinate or needing to use the restroom far more frequently during the day, even when fluid intake remains unchanged. While frequent urination is often caused by urinary tract infections, excessive fluid consumption, or benign prostatic hyperplasia in men, persistent changes without an obvious explanation should not be ignored. According to Pancreatic Cancer UK, new or worsening diabetes symptoms—such as increased urination and thirst—may signal pancreatic dysfunction. If you experience these symptoms, especially in combination with weight loss or fatigue, consult a healthcare provider for blood sugar testing and further assessment.

38. Persistent Gas

Persistent gas, or flatulence, can be a subtle sign of pancreatic cancer, often resulting from the loss of digestive enzymes needed to properly break down food. As the pancreas becomes less effective at producing these enzymes, undigested food passes into the colon, where bacteria ferment it, releasing excess gas. This can lead to ongoing bloating, discomfort, and increased frequency of passing gas, often accompanied by changes in stool consistency or appearance.

While occasional flatulence is normal and commonly linked to dietary factors such as eating beans, certain vegetables, or carbonated drinks, persistent or excessive gas that is not relieved by dietary changes may indicate an underlying digestive problem. According to the Pancreatic Cancer UK, ongoing digestive issues—such as frequent gas, greasy stools, or unexplained abdominal discomfort—deserve medical evaluation, especially in adults over 50 or those with other risk factors. If you notice that you are experiencing more gas than usual for several weeks, with or without other symptoms like weight loss or appetite changes, it is important to consult a healthcare provider for further assessment and potential pancreatic function testing.

39. Burning Sensation in Stomach

A burning sensation in the stomach can sometimes be a less obvious symptom of pancreatic cancer. As a tumor grows, it may disrupt the normal function of the pancreas and adjacent digestive organs, causing irritation or inflammation of the stomach lining or duodenum. This can manifest as a persistent burning or gnawing pain in the upper abdomen, which may radiate to the back or worsen after eating. The discomfort can be subtle and is often mistaken for more common gastrointestinal problems.

Unlike typical stomach ulcers or gastritis—conditions usually linked to infection (Helicobacter pylori), excessive use of NSAIDs, or stress—the burning associated with pancreatic cancer tends to be more persistent and less responsive to standard treatments such as antacids or dietary modifications. According to the Cancer Treatment Centers of America, ongoing upper abdominal burning, especially when accompanied by unexplained weight loss, loss of appetite, or jaundice, should prompt further evaluation. If you experience a burning sensation in your stomach that lasts for several weeks, does not improve with usual remedies, or occurs alongside other warning signs, consult a healthcare provider for a comprehensive assessment.

40. Nighttime Abdominal Discomfort

Nighttime abdominal discomfort is a symptom that can be associated with pancreatic cancer, particularly due to the position of the tumor in relation to surrounding organs and nerves. When lying down, gravity no longer helps keep abdominal organs in a position that minimizes pressure from the mass. This shift can result in increased pressure on the nerves and tissues around the pancreas, making discomfort or pain more pronounced at night or when reclining.

For example, someone may notice that mild abdominal pain or fullness during the day becomes a deep, aching sensation when they try to sleep, often radiating to the back. This pattern differs from pain caused by benign conditions like acid reflux or gas, which often improve with over-the-counter medications and positional changes. According to the Pancreatic Cancer UK, persistent nighttime abdominal pain, especially if it is severe enough to disrupt sleep or is accompanied by other red flags such as weight loss or jaundice, should prompt further investigation. If you experience ongoing discomfort that worsens at night and is not relieved by standard remedies, consult a healthcare provider for evaluation.

41. Early Satiety

Early satiety refers to feeling full after eating only a small amount of food—a symptom that can occur when a pancreatic tumor presses against the stomach or upper intestines. As the mass grows, it can physically restrict the stomach’s capacity or slow the normal passage of food, causing individuals to feel uncomfortably full much sooner than usual. This sensation may be accompanied by bloating, mild nausea, or abdominal discomfort, further reducing the desire or ability to eat.

For example, a person who once finished a full meal may find they can now only manage a few bites before feeling “stuffed,” sometimes to the point of skipping meals altogether. While early satiety can also occur with benign conditions like peptic ulcers or gastroparesis, it usually improves as the underlying issue resolves. If early fullness is persistent and accompanied by unintentional weight loss, fatigue, or other digestive symptoms, it may indicate a more serious problem. According to the Cancer Council Australia, ongoing early satiety should prompt timely medical evaluation to identify the underlying cause and prevent further nutritional decline.

42. Shoulder Pain

42. Shoulder Pain

Shoulder pain can sometimes be a manifestation of referred pain caused by pancreatic tumors. The pancreas is located deep in the abdomen, and when a tumor irritates the diaphragm or adjacent nerves, pain signals can be “referred” to the left or right shoulder. This phenomenon occurs because the nerves serving the diaphragm (the phrenic nerves) share pathways with those supplying the shoulder, leading the brain to misinterpret the source of discomfort. The pain is often described as a dull ache or a deep, persistent sensation that is not relieved by moving or massaging the shoulder.

Unlike typical musculoskeletal shoulder pain, which usually relates to injury, overuse, or arthritis and improves with rest or physical therapy, referred pain from the abdomen is less responsive to such measures and often occurs alongside other symptoms like abdominal discomfort, bloating, or jaundice. According to the Pancreatic Cancer UK, persistent, unexplained shoulder pain—especially if it is not linked to physical activity or trauma and is accompanied by digestive or systemic symptoms—should prompt further medical assessment. Early evaluation can help distinguish between benign musculoskeletal causes and more serious underlying conditions such as pancreatic or other abdominal cancers.

43. Swollen Abdomen

43. Swollen Abdomen

A swollen abdomen, or abdominal distension, can occur in pancreatic cancer due to the buildup of fluid within the abdominal cavity, a condition known as ascites. As tumors progress, they can impair lymphatic drainage, block blood vessels, or spread to the lining of the abdomen, leading to the accumulation of fluid. This fluid buildup causes visible swelling, tightness, or a sense of heaviness in the belly, sometimes making clothing feel tighter or creating discomfort when bending or sitting.

While abdominal swelling is often attributed to overeating, bloating from gas, or benign digestive issues, ascites from cancer is more persistent and may be accompanied by other symptoms such as shortness of breath, loss of appetite, or rapid weight gain from fluid rather than fat. According to the American Cancer Society, unexplained and progressive abdominal swelling—especially if accompanied by jaundice, fatigue, or digestive changes—should prompt medical evaluation. If you notice your abdomen becoming increasingly distended and the swelling does not resolve with routine dietary or lifestyle changes, consult a healthcare provider to determine the cause and receive appropriate treatment.

44. Irregular Heartbeat

44. Irregular Heartbeat
Arrhythmia in pancreatic cancer patients linked to metabolic imbalances and electrolyte disturbances affecting heart rhy…

Irregular heartbeat, or arrhythmia, can occasionally arise in pancreatic cancer patients due to metabolic imbalances that affect the heart’s electrical system. As the pancreas loses its ability to regulate digestion and absorb nutrients, levels of key electrolytes such as potassium, calcium, and magnesium may drop or fluctuate, directly impacting cardiac rhythm. Additionally, malnutrition or dehydration—both common in advanced cancer—can further destabilize heart function, leading to sensations of palpitations, skipped beats, or a racing heart.

For example, someone might notice their heart suddenly fluttering after meals or while resting, or experience brief episodes of dizziness or shortness of breath alongside palpitations. While occasional, mild palpitations are often related to stress, caffeine, or excitement, persistent or severe irregularities—especially when accompanied by chest pain, fainting, or weakness—warrant urgent evaluation. According to the Cancer Council Australia, new or unexplained heart rhythm changes should always be discussed with a healthcare provider, particularly for those with other risk factors or symptoms of pancreatic dysfunction. Early recognition and correction of electrolyte imbalances or other underlying causes can help prevent more serious cardiac complications.

45. Reddened Palms

Reddened palms, also known as palmar erythema, may develop in people with pancreatic cancer, particularly when the disease affects liver function. As pancreatic cancer progresses, it can obstruct the bile ducts or spread to the liver, leading to changes in hormone and blood flow regulation. These alterations can cause the small blood vessels in the palms to dilate, resulting in a noticeable, persistent redness—especially on the thenar and hypothenar eminences (the fleshy areas at the base of the thumb and little finger).

Palmar erythema can also occur in other conditions, such as pregnancy, chronic liver disease, or rheumatoid arthritis, and is usually painless. However, when it appears without an obvious cause or is accompanied by other symptoms—such as jaundice, easy bruising, or fatigue—it may signal underlying liver dysfunction due to pancreatic or other cancers. According to the Cancer Treatment Centers of America, persistent redness of the palms that cannot be attributed to benign causes should prompt a healthcare evaluation. If you notice ongoing palm redness alongside other signs of systemic illness, consult a medical professional to assess for possible liver involvement and underlying malignancy.

46. Bad Breath

Bad breath, or halitosis, can sometimes develop in individuals with pancreatic cancer due to poor digestion and bile backup. When a tumor disrupts the normal flow of bile or impairs pancreatic enzyme production, food may not be properly broken down in the digestive tract. This can lead to the accumulation of undigested food and the growth of odor-producing bacteria in the mouth, stomach, or intestines. Additionally, bile buildup resulting from a blocked bile duct may cause a bitter or metallic taste and contribute to persistent bad breath.

While most cases of halitosis are linked to dental issues, such as gum disease or poor oral hygiene, or to dietary choices like garlic or onions, bad breath caused by pancreatic or digestive problems often persists despite meticulous dental care. According to the Cancer Treatment Centers of America, unexplained and ongoing bad breath—especially when accompanied by digestive complaints, weight loss, or jaundice—should prompt further evaluation. If you notice persistent halitosis despite good oral hygiene and regular dental visits, consult a healthcare provider to assess for underlying digestive or biliary issues that may warrant medical attention.

47. Slow Digestion

Slow digestion, or delayed gastric emptying, can be a subtle but significant symptom of pancreatic cancer. When the pancreas is unable to produce enough digestive enzymes, the breakdown of food in the stomach and small intestine becomes less efficient. As a result, food remains in the digestive tract for longer periods, leading to symptoms such as prolonged fullness, bloating, and discomfort after meals. This can also contribute to malnutrition and unintentional weight loss over time.

For example, a person may notice that large or even modest meals cause them to feel heavy or uncomfortably full for hours, or that their appetite diminishes as digestion slows down. While slow digestion can also result from benign conditions like gastroparesis, overeating, or stress, persistent or progressively worsening symptoms—especially when coupled with unexplained weight loss, greasy stools, or other digestive changes—should not be ignored. According to Pancreatic Cancer UK, ongoing problems with digestion and nutrient absorption may signal underlying pancreatic dysfunction. If you experience ongoing slow digestion that does not improve with dietary changes or routine remedies, consult a healthcare provider for further evaluation and possible pancreatic enzyme testing.

48. Mouth Sores

Mouth sores, or oral ulcers, can develop in individuals with pancreatic cancer due to nutritional deficiencies and changes in immune function. When the pancreas fails to produce sufficient digestive enzymes, the absorption of key vitamins and minerals—such as vitamin B12, folate, and iron—can be compromised. These nutrients are essential for maintaining the health of the mucous membranes lining the mouth. Additionally, the immune suppression associated with cancer may make the oral cavity more susceptible to infections, further increasing the risk of mouth sores.

While most mouth ulcers are linked to minor trauma, stress, or viral infections and typically resolve within a week or two, recurrent or persistent sores that do not heal easily may signal underlying medical issues. According to the Pancreatic Cancer UK, ongoing or severe oral ulcers, especially when accompanied by other symptoms such as weight loss, fatigue, or digestive complaints, should prompt further investigation. If you notice mouth sores that are slow to heal, frequently recur, or are associated with other signs of systemic illness, consult a healthcare provider to determine if nutritional supplementation or additional medical evaluation is needed.

49. Persistent Burping

Persistent burping, or frequent belching, can be a subtle symptom of pancreatic cancer, particularly when it results from ongoing digestive disruption. As pancreatic tumors impair enzyme production and potentially obstruct parts of the digestive tract, food may not be adequately broken down or may pass more slowly through the stomach and intestines. This can cause excess gas to accumulate, which is then expelled as frequent burping. The symptom may be especially noticeable after meals and can sometimes be accompanied by bloating, discomfort, or changes in bowel habits.

In most cases, burping is a benign response to swallowing air while eating or drinking, or to consuming carbonated beverages. However, when burping becomes unusually frequent, lasts for several weeks, or does not improve with dietary changes, it may indicate an underlying digestive problem. According to the Cancer Treatment Centers of America, persistent digestive symptoms, including excessive burping, warrant further evaluation—especially if they are accompanied by weight loss, loss of appetite, or abdominal discomfort. If you notice a significant change in your burping patterns that does not resolve, consult a healthcare provider for assessment and potential testing of pancreatic function.

50. Change in Bowel Habits

A change in bowel habits is a common but often overlooked symptom that can occur with pancreatic cancer. Tumors in the pancreas can interfere with the production of digestive enzymes and disrupt normal bile flow, leading to diarrhea, constipation, or alternating patterns of both. Diarrhea may result from malabsorption of fats and nutrients, producing loose, greasy, or foul-smelling stools. Conversely, tumors that partially block the intestines can slow the passage of stool, causing constipation or infrequent bowel movements.

For example, a person who has always had regular bowel movements may notice sudden and persistent changes, such as needing to go more often, struggling with hard stools, or experiencing episodes of diarrhea that don’t resolve with typical remedies. According to the American Cancer Society, new or unexplained bowel changes—especially if accompanied by other symptoms like weight loss, abdominal pain, or jaundice—should prompt timely medical assessment. If you observe a consistent alteration in bowel habits that lasts for more than a couple of weeks, or if you notice blood in your stool, consult a healthcare provider for further evaluation and testing.
