Pancreatic cancer is one of the most formidable and deadly malignancies worldwide, with an estimated 66,440 new cases and 51,750 deaths projected in the United States in 2024 alone. The overall five-year survival rate remains dismally low—just around 13%—largely due to the cancer’s ability to go unnoticed until advanced stages. The pancreas, a gland tucked deep within the abdomen, is vital for digesting food and regulating blood sugar levels. Yet, by the time symptoms appear, the disease is often too advanced for effective intervention. This tragic reality underscores the urgent need for earlier recognition of subtle pancreatic clues, as detailed by the American Cancer Society.

1. Unexplained Weight Loss

Unintentional weight loss is often one of the earliest and most overlooked signs of pancreatic dysfunction. The pancreas plays a crucial role in breaking down food and regulating how the body uses energy. When cancer or other pancreatic diseases interfere with these processes, the body may struggle to absorb nutrients, resulting in significant and unexplained weight loss.

Consider the story of Mark, a 54-year-old who dismissed his sudden 10-pound drop as the result of a hectic schedule. Only months later, after persistent fatigue and digestive troubles, did he learn the true cause—pancreatic cancer. Such stories are far too common and highlight the subtlety of this warning sign.

Medical experts emphasize that unexplained weight loss, especially when accompanied by other changes such as decreased appetite or persistent gastrointestinal symptoms, warrants medical attention. Early recognition can be life-saving.
According to the National Cancer Institute, rapid weight loss without clear cause should prompt evaluation, particularly in adults over 50. Do not ignore this potential clue—speak with your doctor if you notice sudden changes in weight, as timely intervention could make a critical difference.

2. Persistent Abdominal Pain

Persistent abdominal pain is another frequently missed clue in pancreatic disorders. As tumors develop in or around the pancreas, they can press against nerves or nearby organs, causing a dull, aching pain. This discomfort often settles in the upper abdomen and may radiate through to the back. Unlike common digestive issues such as indigestion or mild gastritis, pancreatic pain is usually constant and worsens over time.

Many people, like Susan—a busy mother who attributed her persistent abdominal aches to stress or diet—ignore this nagging symptom. Unlike fleeting cramps or bloating, the pain associated with pancreatic disease doesn’t resolve with dietary changes or over-the-counter remedies. It may intensify after eating or while lying down, sometimes disrupting sleep.

If you experience ongoing, unrelenting abdominal pain—especially if it’s new or progressively worsening—it’s vital to consult a healthcare provider. According to the Mayo Clinic, persistent pain in this region should never be ignored, as it may signal something far more serious than routine digestive discomfort. Early evaluation can rule out more benign causes and potentially catch pancreatic disease before it advances.

3. Yellowing of Skin or Eyes (Jaundice)

Jaundice—a yellowing of the skin and eyes—is a classic warning sign that should never be dismissed. In pancreatic cancer, this symptom often develops when a tumor blocks the bile duct, preventing bile from draining properly into the intestine. The buildup of bilirubin, a yellow pigment in bile, causes this distinct discoloration.

Consider the case of Linda, who noticed her eyes turning slightly yellow but attributed it to fatigue and poor lighting. She delayed seeking care, thinking it was nothing serious. By the time she saw a doctor, her jaundice had worsened, and her diagnosis was late-stage pancreatic cancer. This story, and many like it, highlight how easy it can be to overlook such a visible symptom.

Jaundice is not normal and should always be evaluated promptly. While it can stem from other conditions such as hepatitis or gallstones, it is especially concerning when accompanied by dark urine or pale stools. As explained by the American Cancer Society, anyone experiencing unexplained yellowing of the skin or eyes should seek immediate medical attention to rule out serious underlying causes—including pancreatic cancer.

4. Dark Urine

Dark urine is often an early but subtle clue of pancreatic dysfunction, particularly when a tumor obstructs the bile duct. The biochemical mechanism behind this lies in the accumulation of bilirubin—a yellowish pigment produced during the normal breakdown of red blood cells. When bile flow is blocked, excess bilirubin escapes into the bloodstream and is filtered out by the kidneys, giving urine a noticeably dark or tea-colored appearance.

Take the example of Robert, who noticed his urine turning brown despite drinking plenty of fluids. He initially assumed dehydration was to blame, but the symptom persisted. Months later, after the appearance of other symptoms, he was diagnosed with pancreatic cancer. This delay, unfortunately, limited his treatment options.

Persistent dark urine should never be ignored, especially if it cannot be explained by diet, medications, or dehydration. According to the Johns Hopkins Medicine, if dark urine is accompanied by other changes—such as jaundice or pale stools—it’s essential to seek medical evaluation promptly. Early testing can rule out benign causes and potentially detect serious conditions, including pancreatic cancer, at a more treatable stage.

5. Light-Colored Stools

Light-colored or pale stools are another subtle but important clue that something may be amiss with the pancreas. Normally, bile produced by the liver and stored in the gallbladder is released into the intestines, helping to digest fats and giving stools their characteristic brown color. When a pancreatic tumor or other obstruction blocks the bile ducts, this flow is disrupted, resulting in stools that appear clay-colored, pale, or even greasy.

This change is often easy to overlook or dismiss, especially if it happens sporadically. However, persistent pale stools are a sign that fat digestion is impaired and that the digestive process is not functioning as it should. Unlike the occasional light stool that may follow a bout of diarrhea or dietary changes, ongoing changes in stool color or consistency should not be ignored.

Monitoring your digestive output is a practical step in catching these early signs. The MD Anderson Cancer Center recommends seeking medical advice if you notice pale, floating, or foul-smelling stools for more than a few days. Early discussion with your doctor can help rule out benign causes and catch potential pancreatic issues sooner.

6. New-Onset Diabetes

The pancreas is central to blood sugar regulation, producing insulin to help the body use glucose for energy. When pancreatic cancer develops, it can disrupt this delicate balance, sometimes leading to new-onset diabetes, especially in adults with no previous risk factors. This phenomenon often precedes a cancer diagnosis by several months.

A comparative case illustrates this link: James, age 62, had always maintained a healthy weight and lifestyle. When he was suddenly diagnosed with type 2 diabetes, his doctor initially attributed it to aging. However, when James began to experience unexplained weight loss and digestive issues, further testing revealed pancreatic cancer as the underlying cause. Such cases underscore how easily new diabetes in older adults can be dismissed or misattributed.

Experts stress that unexplained diabetes after age 50 deserves careful evaluation, particularly if accompanied by other subtle symptoms. According to the National Cancer Institute, sudden diabetes can be an early warning sign of pancreatic cancer. If you or a loved one develops diabetes unexpectedly, especially alongside other changes described in this article, consult your healthcare provider for a thorough assessment.

7. Loss of Appetite

Loss of appetite is a common yet often overlooked symptom that can result from tumors interfering with normal digestive processes. When the pancreas isn’t functioning properly, or when a tumor presses on the stomach and intestines, it can cause a sense of early fullness or even nausea, making eating unappealing. This goes beyond the transient appetite dips many people experience during periods of stress or illness.

Unlike stress-induced appetite loss, which is typically short-lived and improves with emotional recovery or rest, persistent appetite loss due to pancreatic issues tends to be sustained and progressive. For example, Anna, a previously healthy woman, found herself uninterested in meals for weeks, eventually losing weight and feeling weak. Only after discussing these symptoms with her doctor did she discover an underlying pancreatic tumor.

If appetite changes last more than a couple of weeks, or if they occur alongside other symptoms such as weight loss or digestive discomfort, it’s important to seek medical advice. According to Cancer Research UK, chronic loss of appetite can be an early sign of pancreatic cancer or another serious condition and warrants timely evaluation.

8. Nausea and Vomiting

Nausea and vomiting are distressing symptoms that can result when a pancreatic tumor obstructs part of the digestive tract, particularly if the tumor is located near the stomach or duodenum. This blockage slows or stops the normal flow of food, leading to a sensation of fullness, abdominal discomfort, and, eventually, the urge to vomit. Such symptoms often worsen after eating and may become more pronounced over time.

For example, David, a 60-year-old chef, began experiencing persistent nausea and occasional vomiting that didn’t respond to antacids or dietary changes. He initially attributed his symptoms to a stomach bug or food intolerance. However, as the episodes became more frequent and severe, he sought medical care. Imaging studies revealed a mass in his pancreas causing digestive blockage—a diagnosis that came later than it could have.

According to Cedars-Sinai, persistent nausea and vomiting—especially if not linked to identifiable causes—should prompt a thorough medical evaluation, including imaging studies like ultrasound or CT scan. Early detection of the underlying problem can be critical for improving outcomes and expanding treatment options.

9. Back Pain

Back pain is a surprisingly common symptom in people with pancreatic cancer, yet it is often misattributed to muscle strain or spinal issues. Pancreatic tumors, particularly those in the body or tail of the gland, can press on nearby nerves or tissues, causing what is known as referred pain—pain that is felt in an area distant from its source. This pain is typically located in the mid-to-upper back and may be dull, constant, and unresponsive to typical remedies for muscle pain.

Unlike ordinary back pain from poor posture, lifting, or injury, pancreatic-related back pain often doesn’t improve with rest, stretching, or physical therapy. For instance, Maria, who had always been active, noticed persistent aching in her upper back that worsened at night and wasn’t relieved by her usual self-care techniques. This distinct pattern warranted further investigation, ultimately leading to a pancreatic cancer diagnosis.

A helpful tip for recognizing suspicious pain is to track when the discomfort occurs and how it responds to movement or medication. According to American Cancer Society, back pain that is persistent, progressive, and unrelated to activity should prompt medical evaluation to rule out serious underlying causes.

10. Fatigue

Fatigue—an overwhelming sense of tiredness or lack of energy—is a common symptom in many illnesses, but it can be a particularly telling clue in pancreatic cancer. The fatigue associated with cancer is systemic, meaning it affects the entire body and does not improve with rest or sleep. Unlike ordinary tiredness from a busy week or insufficient sleep, cancer-related fatigue lingers and can interfere with daily activities, motivation, and overall quality of life.

For example, Tom, a 58-year-old office worker, found himself unable to get through the day without multiple naps and struggled to concentrate on simple tasks. He initially blamed aging and work stress, but when his exhaustion persisted for weeks despite rest and lifestyle changes, he sought medical advice. This led to further tests, which revealed advanced pancreatic cancer.

According to Cancer.Net, persistent, unexplained fatigue warrants a visit to your healthcare provider, especially if it is accompanied by other symptoms discussed in this article. Early assessment can help identify the root cause and, when appropriate, lead to timely intervention or further testing for underlying conditions like pancreatic cancer.

11. Blood Clots

11. Blood Clots

Pancreatic cancer is known to significantly increase the risk of blood clots, a complication that can sometimes be the first sign of an underlying malignancy. These clots, known as venous thromboembolism (VTE), may form in the legs (deep vein thrombosis) or travel to the lungs (pulmonary embolism), both of which can be life-threatening. The biochemical changes brought on by the tumor make blood more prone to clotting, even in otherwise healthy individuals.

Consider the case of Patricia, a 63-year-old woman who developed swelling and pain in her calf—classic symptoms of a blood clot. With no history of trauma, surgery, or prolonged immobility, her doctors were puzzled. Further investigation revealed pancreatic cancer, explaining her body’s newfound tendency to form clots. Stories like Patricia’s highlight the importance of recognizing unexpected blood clots as a possible cancer warning.

According to the American Cancer Society, unexplained blood clots—especially in older adults or those with additional symptoms—should prompt thorough evaluation for underlying causes, including pancreatic cancer. Early recognition and intervention can reduce complications and lead to more timely diagnoses.

12. Itchy Skin

12. Itchy Skin

Itchy skin, or pruritus, can sometimes signal a problem deeper than a simple allergic reaction. In pancreatic cancer, when a tumor blocks the bile duct, bile salts and bilirubin accumulate in the bloodstream and tissues. This buildup can irritate nerve endings in the skin, producing a persistent, often maddening itch that is not relieved by moisturizers or antihistamines. The sensation may be generalized but often becomes most pronounced on the hands and feet.

Unlike itching from allergies or contact dermatitis—which is usually accompanied by a rash, redness, or swelling—itchiness from bile buildup tends to occur without obvious skin changes. For instance, Greg, a 59-year-old retiree, experienced relentless itching for weeks. Over-the-counter remedies offered no relief, and only after other symptoms appeared did he learn his pancreatic tumor was to blame.

According to American Cancer Society, unexplained, persistent itching—especially when paired with jaundice or dark urine—should prompt a medical evaluation. Ignoring this symptom can delay detection of serious underlying issues, making it crucial to seek further investigation if itching is severe or ongoing.

13. Indigestion and Bloating

Indigestion and bloating are common digestive complaints, but when they persist, they may signal something more serious than simple functional indigestion. The pancreas produces vital enzymes that help break down fats, proteins, and carbohydrates. When a tumor disrupts enzyme production or flow, food isn’t digested properly, leading to ongoing indigestion, bloating, and discomfort after meals.

Occasional bloating or mild indigestion typically resolves with dietary adjustments or stress reduction. However, when these symptoms become frequent or severe—even with no clear dietary triggers—they may reflect digestive enzyme insufficiency, a hallmark of pancreatic dysfunction. For example, Carla, a 57-year-old teacher, noticed worsening bloating and nausea that did not improve with antacids or probiotics. Only after months of tracking her symptoms did she discover a pancreatic tumor was the underlying cause.

The Pancreatic Cancer Action Network recommends keeping a symptom diary to note patterns and persistence of digestive complaints. If indigestion or bloating lasts more than a few weeks, or is accompanied by other warning signs, seek medical advice. Early investigation is key to distinguishing minor issues from potential pancreatic disease.

14. Greasy or Oily Stools (Steatorrhea)

14. Greasy or Oily Stools (Steatorrhea)

Greasy or oily stools, a condition known as steatorrhea, are a telltale sign of fat malabsorption. The pancreas is responsible for producing enzymes that help digest fats. When a tumor or chronic inflammation disrupts this process, undigested fat passes through the intestines and appears in the stool. These stools may float, look pale or clay-colored, and be difficult to flush. They often have a particularly foul odor and may leave an oily residue in the toilet bowl.

Imagine Sarah, a 61-year-old who began to notice that her stools were unusually loose and shiny, with a persistent greasy quality despite no changes in her diet. She initially felt embarrassed to mention this to her doctor, but as the symptoms persisted and she began to lose weight, she finally sought medical advice. Further testing revealed pancreatic insufficiency caused by a tumor.

The Cancer Treatment Centers of America stress the importance of discussing persistent stool changes with your healthcare provider. Consistent greasy, oily, or floating stools—especially with other digestive symptoms—should not be ignored and may warrant further evaluation for pancreatic issues.

15. Sudden Intolerance to Fatty Foods

15. Sudden Intolerance to Fatty Foods

A sudden intolerance to fatty foods is often an overlooked but important clue of pancreatic insufficiency. The pancreas produces enzymes essential for fat digestion; when its function is compromised by cancer or chronic inflammation, the body struggles to break down dietary fats. As a result, meals rich in butter, cheese, or oils may trigger bloating, cramping, diarrhea, or nausea.

This intolerance is frequently confused with gallbladder disease, as both conditions can produce similar symptoms after eating fatty foods. However, while gallbladder attacks tend to be acute and severe, pancreatic insufficiency causes a more subtle and chronic pattern of digestive distress. For example, John, a 56-year-old man who had always enjoyed pizza and fried foods, began experiencing stomach upset and loose stools every time he indulged, ultimately prompting him to seek medical advice.

According to the National Pancreas Foundation, persistent intolerance to fatty meals—especially when it develops suddenly or occurs alongside other digestive changes—should not be ignored. If these symptoms persist, consult your healthcare provider for evaluation and to rule out underlying pancreatic disease.

16. Unexplained Fever

Unexplained, persistent low-grade fevers can sometimes be an early clue to the presence of cancer, including pancreatic cancer. The body’s immune response to a tumor or the inflammation caused by cancer can trigger recurrent fevers without a clear source of infection. Unlike fevers associated with the flu or other infections—which are typically accompanied by chills, body aches, or respiratory symptoms—cancer-related fevers tend to be milder, more persistent, and often occur without any obvious cause.

For instance, Alan, a 64-year-old retiree, noticed he was running a mild fever several times a week. He had no cough, sore throat, or urinary symptoms. Because the fevers were not severe, he put off seeing his doctor until additional symptoms—such as fatigue and abdominal discomfort—appeared. Eventually, he was diagnosed with pancreatic cancer.

According to the American Cancer Society, persistent or unexplained fevers—especially those lasting more than a week—should not be dismissed. If you are experiencing this symptom without clear signs of infection, it is wise to consult your healthcare provider for further evaluation, as it may signal a serious underlying issue.

17. Swollen Gallbladder

A swollen gallbladder can be an indirect but telling sign of pancreatic cancer. When a tumor grows in or near the head of the pancreas, it may compress the bile ducts, preventing bile from draining properly. This blockage causes bile to back up, leading to gallbladder distention—a condition that can sometimes be felt as a mass below the right rib cage or detected on imaging studies.

This scenario differs from gallstones, which also cause gallbladder swelling but usually present with sharp, episodic pain and often trigger infection or inflammation (cholecystitis). In contrast, pancreatic cancer-related swelling tends to be more insidious and painless at first, though it may be accompanied by jaundice or digestive complaints.

The American Cancer Society highlights that worrisome warning signs include persistent right upper abdominal fullness, unexplained jaundice, or sudden changes in digestion. If you notice any of these symptoms, or if your doctor detects a swollen gallbladder during an exam or scan, further investigation is warranted. Early diagnosis can be crucial for improving treatment options and outcomes.

18. Nonspecific Digestive Changes

Pancreatic cancer often presents with nonspecific digestive changes that can be difficult to pinpoint. These might include mild, persistent nausea, irregular bowel habits, vague abdominal discomfort, or a general sense of fullness after eating small amounts. Such symptoms are easily mistaken for less serious conditions, leading many people to delay seeking help.

These vague complaints often overlap with those of irritable bowel syndrome (IBS), a far more common and typically benign disorder. For example, IBS usually causes symptoms to fluctuate and improve with dietary adjustments or stress management, while pancreatic cancer-related changes tend to worsen over time and seldom respond to simple remedies.

The National Cancer Institute emphasizes the importance of persistence in evaluation if digestive symptoms are new, progressive, or unresponsive to usual treatments. If you notice ongoing changes—especially in combination with other warning signs—advocate for further testing. Early and thorough assessment can make all the difference in catching pancreatic cancer before it reaches an advanced stage.

19. Difficulty Swallowing

19. Difficulty Swallowing

Difficulty swallowing, or dysphagia, can sometimes develop as a pancreatic tumor expands and presses on nearby digestive structures. When the tumor invades or compresses the duodenum (the first part of the small intestine) or other adjacent organs, it can partially obstruct the passage of food from the stomach, leading to a sensation of food getting “stuck,” frequent coughing or choking, and sometimes pain when swallowing.

This symptom is easily confused with acid reflux or gastroesophageal reflux disease (GERD), conditions which also cause discomfort or burning in the chest after eating. However, reflux symptoms are often relieved with antacids or lifestyle changes, whereas pancreatic cancer-related swallowing difficulties usually worsen over time and persist despite treatment.

According to the Cancer Treatment Centers of America, persistent or progressive difficulty swallowing—especially when accompanied by weight loss, appetite changes, or persistent nausea—warrants prompt medical assessment. Early evaluation can help distinguish between benign digestive issues and more serious causes, allowing for timely diagnosis and intervention.

20. Enlarged Lymph Nodes

20. Enlarged Lymph Nodes

Enlarged lymph nodes can be an important, though often overlooked, clue in pancreatic cancer. Lymph nodes are small glands that function as part of the body’s immune system, filtering harmful substances and mounting a response to infection or disease. When cancer cells spread from the pancreas, they may lodge in nearby lymph nodes, causing them to swell as the immune system reacts to the malignant invasion.

Swollen lymph nodes due to infection are typically tender, soft, and may resolve within a week or two. In contrast, cancer-related lymph node enlargement often feels firmer, is generally painless, and persists or grows over time. For instance, some individuals may notice a lump above the collarbone (supraclavicular node) or in the abdomen, which their doctor detects during a physical exam or imaging.

The American Cancer Society suggests that enlarged, persistent, or unexplained lymph nodes—especially in older adults or those with other pancreatic warning signs—should always be evaluated by a healthcare professional. Next steps usually include imaging studies or a biopsy to determine the underlying cause and direct appropriate treatment.

21. Hiccups That Don’t Go Away

Most people experience hiccups occasionally, often triggered by eating too quickly, drinking carbonated beverages, or sudden excitement. These benign episodes resolve within minutes or hours. However, persistent hiccups lasting more than 48 hours can be a sign of an underlying medical problem, including pancreatic cancer. When a tumor in the pancreas or nearby organs irritates the diaphragm—the muscle that controls breathing—it may trigger repeated, uncontrollable hiccup spasms.

Unlike common hiccups, those caused by irritation or pressure on the diaphragm tend to be stubborn and resistant to usual home remedies. For example, Richard, a 65-year-old, endured days of relentless hiccups accompanied by mild abdominal discomfort. When over-the-counter solutions failed, he sought medical attention and further testing revealed a pancreatic mass pressing against his diaphragm.

According to the Johns Hopkins Medicine, unrelenting hiccups—especially when paired with other worrisome symptoms—should prompt a visit to your healthcare provider. Persistent hiccups may be a rare but important warning sign of a deeper issue, and early evaluation can help catch serious conditions before they progress.

22. Change in Taste Preferences

22. Change in Taste Preferences

A sudden or persistent change in taste preferences can be an overlooked sign of pancreatic disease. Tumors or inflammation may alter how the body digests food, impact saliva production, or cause subtle chemical changes in the mouth, resulting in altered taste perception. People might find their favorite foods now taste bland, metallic, or even unpleasant, leading to reduced enjoyment of meals or a tendency to avoid certain foods altogether.

For example, Linda, a 62-year-old with no prior health issues, began noticing that coffee and chocolate—her long-time favorites—tasted bitter and off-putting. At first, she attributed it to aging or medication. But when this persisted and she lost interest in eating, she eventually sought medical advice. Further evaluation revealed underlying pancreatic dysfunction.

According to Cancer Treatment Centers of America, tracking persistent changes in taste or appetite can aid in early detection of underlying health issues. If these changes last for weeks or interfere with nutrition and enjoyment of food, it’s wise to discuss them with a healthcare provider, especially if other digestive symptoms are present.

23. Night Sweats

23. Night Sweats

Night sweats—episodes of excessive sweating during sleep—can sometimes be a symptom of underlying cancer, including pancreatic cancer. This occurs because certain tumors disrupt the body’s normal temperature regulation through the release of inflammatory chemicals called cytokines. Unlike the mild sweating that may accompany a warm room or heavy blankets, cancer-related night sweats are usually drenching, often requiring a change of clothes or bed linens.

Night sweats can also be caused by hormonal changes, such as menopause, thyroid disorders, or infections. However, those related to cancer tend to be persistent and are often accompanied by other symptoms such as unexplained weight loss or fevers. For instance, George, a 60-year-old man, began waking up soaked several nights a week, even in a cool room. When this persisted and he experienced additional fatigue and appetite loss, he consulted his doctor and was later diagnosed with pancreatic cancer.

The American Cancer Society advises that persistent, unexplained night sweats—especially when paired with other concerning signs—should prompt further workup by a healthcare professional to rule out serious causes, including malignancy.

24. Depression or Sudden Mood Changes

Depression, anxiety, or sudden mood changes can sometimes be the first noticeable signs of pancreatic disease. Research suggests that pancreatic cancer, in particular, can disrupt the body’s chemical balance, contributing to mood disturbances even before physical symptoms emerge. Inflammatory mediators and metabolic changes may influence neurotransmitters, leading to feelings of sadness, irritability, or loss of interest in activities once enjoyed.

This is distinct from reactive depression, which arises in response to life stressors or illness. Depression linked to pancreatic disease often appears abruptly and may seem out of proportion to external circumstances. For example, Emily, a 60-year-old woman with no history of mental health issues, developed persistent low mood and anxiety without a clear trigger. Over time, as digestive symptoms surfaced, further evaluation revealed pancreatic cancer.

According to Pancreatic Cancer Action Network, new or unexplained emotional changes—especially in older adults—should prompt holistic assessment, including evaluation for physical causes. Addressing both mental and physical health concerns is essential for accurate diagnosis and comprehensive care.

25. Paleness or Anemia

25. Paleness or Anemia

Paleness or a washed-out appearance—often most noticeable in the face or inner eyelids—can be a sign of anemia, a condition where the body lacks enough healthy red blood cells to transport oxygen. Chronic illnesses like pancreatic cancer can cause anemia by interfering with nutrient absorption, causing internal bleeding, or triggering inflammation that suppresses blood cell production. This is known as “anemia of chronic disease.”

Unlike anemia caused by iron or vitamin deficiencies, which often results from poor diet or heavy menstruation, anemia linked to cancer tends to develop gradually and is less likely to respond to dietary changes alone. For example, Michael, a 67-year-old man, noticed he was looking pale and feeling weak, even though his eating habits hadn’t changed. Bloodwork revealed low hemoglobin levels, prompting further investigation and a diagnosis of pancreatic cancer.

The American Cancer Society recommends seeking blood tests if you experience persistent fatigue, unexplained weakness, or paleness. Early identification of anemia can help uncover underlying conditions, including pancreatic disease, and guide appropriate treatment.

26. Swelling in the Legs (Edema)

Swelling in the legs, or edema, can be an underappreciated sign of pancreatic cancer. Tumors can block blood flow in major abdominal veins, causing fluid to leak into the tissues of the lower extremities. In some cases, cancer may also trigger blood clots (deep vein thrombosis), which further contribute to swelling. This type of edema is often persistent, affecting one or both legs, and may worsen as the day goes on.

It’s important to distinguish cancer-related edema from swelling caused by heart failure or kidney disease. Heart failure typically produces swelling in both legs and is often accompanied by shortness of breath or weight gain, while edema from pancreatic cancer may be more localized and develop without other cardiac symptoms. For example, Diane, a 68-year-old, noticed her right leg was consistently swollen and tender. After her doctor ruled out heart issues, further imaging revealed a tumor compressing a major vein.

The Cancer Treatment Centers of America recommend timely evaluation of new or unexplained leg swelling. If you notice persistent swelling, especially with other symptoms, seek medical attention to rule out underlying causes, including pancreatic disease.

27. Early Satiety (Feeling Full Quickly)

27. Early Satiety (Feeling Full Quickly)

Early satiety, or the sensation of feeling full after eating only a small amount, can be a warning sign of pancreatic cancer. Tumors in or around the pancreas may press against the stomach or intestines, reducing the stomach’s capacity to expand normally or slowing gastric emptying. This pressure can quickly cause a sense of fullness or bloating, even when only a modest amount of food has been consumed.

While early satiety can also occur with functional dyspepsia—a benign disorder often related to stress or minor digestive issues—it typically resolves on its own or with simple dietary adjustments. In contrast, tumor-related early satiety tends to persist and may be accompanied by weight loss, nausea, or other digestive changes. For example, Sam, a 59-year-old, noticed he could barely finish half his usual meal before feeling uncomfortably full, prompting him to see his doctor.

The Pancreatic Cancer Action Network advises that persistent early satiety—especially when paired with other worrisome symptoms—should prompt further medical evaluation. If you regularly feel full quickly, don’t ignore this change; timely assessment is key to ruling out serious causes.

28. Poor Wound Healing

Poor wound healing is a subtle but important sign that can be linked to pancreatic cancer. The disease often leads to malnutrition by interfering with digestion and nutrient absorption, depriving the body of essential building blocks for tissue repair. As a result, even minor cuts or scrapes may take longer to heal, and wounds may become more prone to infection. This issue can be compounded by weight loss and muscle wasting, both common in advanced pancreatic disease.

This symptom can resemble the poor healing seen in uncontrolled diabetes, where high blood sugar impairs circulation and immune response. However, in pancreatic cancer, the underlying cause is a lack of proteins, vitamins, and minerals due to digestive insufficiency. For instance, Laura, a 65-year-old, noticed her small injuries lingered for weeks and were slow to close—a change that, in hindsight, was an early warning of her pancreatic condition.

According to the Cancer Treatment Centers of America, persistent poor wound healing—especially if accompanied by weight loss, fatigue, or other digestive symptoms—should be investigated by a healthcare provider. Don’t dismiss ongoing healing problems, as they may signal a deeper nutritional or medical issue.

Heart palpitations—sensations of a racing, fluttering, or pounding heartbeat—can sometimes arise in people with pancreatic cancer. One reason is that digestive problems linked to pancreatic disease can cause electrolyte imbalances, especially when malabsorption leads to low levels of potassium, calcium, or magnesium. These minerals are crucial for normal heart rhythm, and their depletion can make the heart beat irregularly or more forcefully.

While anxiety and stress are the most common causes of palpitations, those due to pancreatic or digestive issues tend to occur alongside other symptoms, such as muscle cramps, fatigue, or persistent digestive changes. Unlike anxiety-related palpitations, which often resolve with relaxation, palpitations from electrolyte disturbances may persist until the underlying cause is addressed.

The Cancer Treatment Centers of America recommend investigating new, persistent, or unexplained heart palpitations—especially when accompanied by digestive symptoms or general malaise. If you experience ongoing palpitations, don’t assume they’re just from stress; ask your healthcare provider for a thorough evaluation to check for hidden imbalances or more serious conditions.

30. Chronic Constipation

Chronic constipation can be a subtle warning sign of pancreatic cancer, particularly when it develops alongside other digestive changes. The pancreas and bile ducts play a crucial role in regulating digestion. When tumors block or compress these ducts, the flow of bile and pancreatic enzymes is reduced, slowing the movement of food through the intestines. This can lead to persistent constipation, hard stools, and a sense of incomplete evacuation.

Functional constipation—commonly caused by dietary factors, dehydration, or lack of exercise—often improves with increased fiber intake or lifestyle adjustments. In contrast, constipation linked to pancreatic dysfunction tends to be more resistant to these simple remedies and may worsen over time. For example, Paul, a 70-year-old, noticed his usual remedies for constipation no longer worked, and his bowel habits became progressively more sluggish.

The American Cancer Society notes that persistent, unexplained constipation—especially when accompanied by other symptoms such as abdominal pain, weight loss, or nausea—should prompt medical evaluation. Early investigation can help distinguish minor digestive issues from more serious, underlying conditions like pancreatic cancer.

31. Frequent Infections

Frequent or recurrent infections can be a sign that the body’s immune system is under strain—a common occurrence in people with pancreatic cancer. As the disease progresses, cancer cells and the associated inflammation can suppress normal immune function, making it harder for the body to fight off bacteria, viruses, and other pathogens. This immune suppression may result in repeated episodes of respiratory, urinary, or skin infections that take longer to resolve or respond poorly to standard treatments.

In healthy adults, it’s typical to experience a few mild infections each year, particularly during cold and flu season. However, if you or a loved one begins to notice infections occurring more frequently, lasting longer, or requiring multiple courses of antibiotics, this could be a red flag for an underlying health problem. For instance, Karen, a 66-year-old, found herself battling back-to-back urinary tract infections and bronchitis. Her doctor eventually uncovered a pancreatic tumor compromising her immune response.

The Cancer Treatment Centers of America recommend seeking further evaluation if you notice a sudden increase in the number or severity of infections. Persistent immune changes warrant thorough testing to identify any underlying medical conditions, including cancer.

32. Gassy or Burping More Than Usual

32. Gassy or Burping More Than Usual

Excessive gas or frequent burping can be a sign of pancreatic enzyme insufficiency—a common complication of pancreatic cancer. The pancreas produces enzymes necessary for breaking down fats, proteins, and carbohydrates. When its function is disrupted by a tumor or inflammation, undigested food can ferment in the gut, producing more gas and leading to bloating, flatulence, and increased belching.

It’s normal to experience some gas after eating certain foods, like beans, broccoli, or carbonated drinks. However, if you notice a sudden or persistent increase in gas or burping that doesn’t improve with dietary changes, it may be a sign that your pancreas isn’t producing enough enzymes. For example, Martin, a 63-year-old, began having embarrassing bouts of gas and burping after every meal, regardless of what he ate. After months of symptoms, he was diagnosed with pancreatic insufficiency due to cancer.

The Pancreatic Cancer Action Network suggests monitoring persistent digestive changes. If increased gas or burping lasts for several weeks or is accompanied by other symptoms, consult your healthcare provider to rule out enzyme insufficiency or more serious conditions like pancreatic cancer.

33. Muscle Wasting

Muscle wasting, or cancer cachexia, is a significant concern in people with pancreatic cancer. This syndrome involves rapid and involuntary loss of muscle mass, often accompanied by weight loss and weakness. The cancer’s interference with nutrient absorption, increased metabolic demands, and chronic inflammation all contribute to this debilitating condition. Unlike typical age-related muscle loss, cachexia is swift and difficult to reverse with regular diet or exercise.

Consider the case of Robert, a 65-year-old who noticed his arms and legs becoming noticeably thinner despite eating as much as usual. He grew weaker and struggled with everyday tasks. After a medical evaluation, he learned that pancreatic cancer and digestive enzyme insufficiency were behind his sudden muscle loss.

According to the American Cancer Society, early nutrition support is crucial for people experiencing unexplained muscle wasting. If you or a loved one notices rapid muscle loss, especially with fatigue or digestive symptoms, seek prompt medical advice. Early intervention can help maintain strength, improve quality of life, and potentially slow the progression of cachexia.

34. Fluctuating Blood Sugar

34. Fluctuating Blood Sugar

The pancreas is a central player in blood sugar regulation, producing hormones such as insulin and glucagon that keep glucose levels stable. When the pancreas is affected by cancer or chronic disease, these hormone levels can become unpredictable, resulting in fluctuating blood sugar. This instability can cause episodes of low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia), often without a clear dietary trigger.

Unlike classic type 2 diabetes, which typically develops gradually and is usually managed with lifestyle changes or medication, pancreatic-related blood sugar swings may occur rapidly and be harder to control. For example, Helen, a 70-year-old, noticed she was dizzy and shaky after meals one day and unusually thirsty and fatigued the next. Her doctor found erratic blood glucose readings, prompting further tests that revealed pancreatic dysfunction.

The Cancer Treatment Centers of America note that unexplained or rapidly fluctuating blood sugar—especially in people without a prior history of diabetes—should prompt evaluation for pancreatic causes. If you notice new or unpredictable changes in your blood sugar, consult your healthcare provider to rule out underlying pancreatic disease.

35. Chronic Cough

35. Chronic Cough

A chronic cough is an uncommon but significant symptom that may be linked to pancreatic cancer, especially when the disease involves nerves near the diaphragm or has metastasized to the lungs or chest cavity. Tumor growth can irritate the phrenic or vagus nerves, leading to persistent coughing episodes that do not resolve with standard cold or allergy treatments. Additionally, metastasis to the lungs or pleura can cause cough, shortness of breath, or chest discomfort.

Unlike the cough of a common cold or respiratory infection—which is usually short-lived and accompanied by fever, congestion, or sore throat—cancer-related cough tends to be dry, persistent, and unresponsive to over-the-counter remedies. For instance, Susan, 68, battled a nagging cough for months. Despite several courses of antibiotics, her cough persisted, prompting her doctor to order further imaging that revealed metastatic pancreatic cancer.

The Cancer Treatment Centers of America emphasize that persistent, unexplained cough—especially if it lasts for weeks or is accompanied by weight loss or other symptoms—should prompt further evaluation. Chronic cough deserves attention as a potential warning sign of deeper systemic illness.

36. Swelling in Abdomen (Ascites)

Swelling in the abdomen, known as ascites, is a potential complication of advanced pancreatic cancer. Ascites occurs when fluid accumulates in the abdominal cavity, often due to blockage of lymphatic drainage or irritation of the peritoneum by cancer cells. This fluid buildup can cause noticeable abdominal distention, a feeling of heaviness, discomfort, and even difficulty breathing or moving comfortably.

Ascites is also commonly seen in liver disease, where scarring disrupts normal blood flow and fluid balance. However, in pancreatic cancer, ascites typically develops alongside other signs like weight loss, jaundice, or digestive changes. For example, Frank, a 72-year-old, noticed his belly was steadily growing despite a loss of appetite and body weight. A medical workup found excess fluid caused by metastatic pancreatic cancer.

The American Cancer Society advises that unexplained, persistent abdominal swelling should always prompt medical evaluation. If you or a loved one develops new-onset abdominal distention, seek care as soon as possible to determine the cause and begin appropriate treatment, as early intervention can ease symptoms and improve outcomes.

37. Visible Veins on Abdomen

The appearance of visible, engorged veins on the abdomen can be a sign of a serious underlying condition such as portal hypertension. In the context of pancreatic cancer, this complication may arise when a tumor blocks the portal vein or its branches, disrupting normal blood flow from the intestines to the liver. As pressure builds, blood is forced through smaller collateral veins, causing them to become dilated and visible beneath the skin—a pattern sometimes called “caput medusae.”

Similar changes are seen in advanced liver disease, such as cirrhosis, where scar tissue impedes blood movement and leads to the same backup. However, in pancreatic cancer, these visible veins often develop more rapidly and are frequently accompanied by other symptoms like abdominal swelling, jaundice, or unintended weight loss. For instance, Mark, a 71-year-old, noticed blue, rope-like veins appearing across his belly along with persistent bloating. Imaging ultimately revealed a pancreatic tumor compressing his portal vein.

The American Cancer Society notes that sudden or prominent abdominal veins warrant a prompt medical evaluation. Don’t ignore this visible change, as it may indicate a blockage or increased pressure related to a serious internal condition.

38. Unusual Bruising

38. Unusual Bruising

Unusual or easy bruising can be a sign of disrupted blood clotting—a complication sometimes seen in pancreatic cancer. The pancreas helps regulate digestive processes and hormone balance, but when it’s affected by disease, it can also impact the liver’s production of clotting factors. This imbalance, along with potential vitamin K deficiency from fat malabsorption, can make people more prone to bruising even after minor bumps or injuries.

This symptom is often confused with the side effects of blood thinners like warfarin or aspirin, which also increase bruising risk. However, if you’re not taking such medications and notice new, unexplained bruises—especially in unusual places like the abdomen, back, or legs—it could point to an underlying medical issue. For example, Nancy, a 64-year-old, began finding large purple spots on her arms and thighs. She wasn’t on any blood thinners, and further testing revealed pancreatic dysfunction affecting her clotting system.

The Cancer Treatment Centers of America recommend medical evaluation for any unexplained or persistent bruising. If bruises appear easily or without clear cause, consult your healthcare provider to rule out pancreatic or other systemic diseases.

39. Persistent Hiccups

While hiccups are generally harmless and fleeting, persistent or recurring hiccups can sometimes be a rare warning sign of a deeper health problem, including pancreatic cancer. These stubborn hiccups may occur when a tumor irritates the diaphragm or the nerves that control its movement, disrupting the normal rhythm of breathing and swallowing. Such hiccups can last for days or even weeks, often interfering with sleep and daily activities.

Benign hiccups typically have obvious triggers, like eating too quickly, drinking carbonated beverages, or experiencing sudden excitement. They usually resolve on their own or with simple home remedies. In contrast, persistent hiccups—those lasting more than 48 hours, or frequently recurring without clear cause—deserve more attention. For example, Tom, a 67-year-old, noticed his hiccups would return daily and last for hours at a time. After his doctor ruled out common causes, further workup revealed a pancreatic tumor pressing against his diaphragm.

According to Johns Hopkins Medicine, persistent or unexplained hiccups should prompt medical evaluation—especially if they accompany other concerning symptoms. Early investigation can help identify and address serious underlying issues before they worsen.

40. High Blood Pressure

Though not among the most common symptoms, high blood pressure (hypertension) can sometimes develop as a secondary effect of pancreatic cancer. Stress from chronic illness, pain, or anxiety may raise blood pressure, and metabolic changes caused by pancreatic dysfunction—such as fluid retention, electrolyte imbalances, or even hormone secretion by rare pancreatic tumors—can also contribute. This form of secondary hypertension may arise suddenly and prove difficult to control with standard medications.

Primary hypertension, by contrast, typically develops gradually and is more often linked to genetics, aging, or lifestyle factors such as diet and physical activity. When high blood pressure appears abruptly or worsens despite treatment—especially if accompanied by other unexplained symptoms such as weight loss, digestive changes, or swelling—it may indicate an underlying medical issue that deserves further attention.

The Cancer Treatment Centers of America recommend seeking medical advice for new or difficult-to-treat high blood pressure. If your blood pressure rises unexpectedly or is resistant to standard therapy, discuss these changes with your healthcare provider to ensure that a hidden pancreatic or systemic illness is not overlooked.

41. Swollen Spleen

41. Swollen Spleen

A swollen spleen, or splenomegaly, can develop as a result of a tumor-related blockage in the blood vessels that drain the spleen. In pancreatic cancer, if a tumor compresses the splenic vein or portal vein, blood flow out of the spleen becomes restricted, causing the organ to enlarge. This may result in a sensation of fullness or discomfort in the upper left abdomen, and sometimes even visible distention.

Swollen spleen is also seen in infections like mononucleosis or certain liver diseases. Infection-related splenomegaly typically resolves as the infection improves, while cancer-related splenomegaly tends to persist or worsen over time. For example, Jim, a 69-year-old, noticed a dull ache below his left rib cage and felt unusually full even after small meals. Imaging revealed a pancreatic tumor compressing his splenic vein, resulting in splenomegaly.

The American Cancer Society emphasizes that persistent or unexplained spleen enlargement always warrants further investigation with imaging studies. If you or your doctor notice this change, prompt evaluation is important to identify the underlying cause and plan appropriate treatment.

42. Loss of Interest in Usual Activities

A significant loss of interest in usual activities—social withdrawal, giving up hobbies, or avoiding favorite pastimes—can reflect both mood and physical energy changes associated with chronic illnesses like pancreatic cancer. The ongoing fatigue, discomfort, and metabolic changes brought on by the disease can drain motivation and pleasure from life, often before more obvious physical symptoms emerge. This change is sometimes misattributed to aging, life stress, or burnout.

Situational burnout or temporary loss of enthusiasm, such as after a busy season at work or personal upheaval, typically improves with rest, support, or a change in routine. However, loss of interest driven by an undiagnosed illness like pancreatic cancer is more likely to persist and worsen, often accompanied by other subtle symptoms such as fatigue, appetite loss, or mood disturbances. For example, Alice, a 63-year-old, gradually stopped participating in her book club and gardening, feeling “off” and unable to muster her usual excitement. Medical evaluation eventually revealed advanced pancreatic cancer.

According to the Pancreatic Cancer Action Network, persistent disinterest or withdrawal should prompt consideration of both mental and physical health causes. When the change is unexplained or unrelenting, a whole-body evaluation can help identify underlying medical issues and guide appropriate care.

43. Frequent Heartburn

Frequent heartburn—a burning sensation in the chest or throat—can sometimes be a sign of pancreatic dysfunction rather than simple acid reflux. When the pancreas isn’t producing enough digestive enzymes, undigested food can linger in the stomach and intestines, leading to increased acid production and irritation of the esophagus. This can mimic or worsen symptoms of classic heartburn, making it easy to mistake one for the other.

Classic heartburn from gastroesophageal reflux disease (GERD) usually responds well to over-the-counter antacids or dietary changes. In contrast, heartburn caused by underlying pancreatic issues may persist despite these measures and is often accompanied by other digestive symptoms such as bloating, nausea, or unexplained weight loss. For instance, Grace, a 60-year-old, found herself needing heartburn medication daily for the first time in her life, but her symptoms didn’t improve until her doctor investigated further and discovered pancreatic disease.

The Cancer Treatment Centers of America stress that persistent or worsening heartburn—especially when new in middle age or accompanied by other symptoms—should prompt a thorough medical evaluation. Don’t ignore ongoing heartburn, as it may signal an underlying pancreatic or systemic problem.

44. Swollen Face or Neck

44. Swollen Face or Neck

Swelling in the face or neck is an uncommon but concerning symptom in pancreatic cancer, usually resulting from vascular obstruction. If a tumor compresses large veins—such as the superior vena cava, which drains blood from the upper body—fluid can back up, leading to puffiness and swelling in the face, neck, or even the arms. This is known as superior vena cava syndrome, and it can develop rapidly or over several days.

Unlike swelling from allergic reactions, which is often accompanied by itching, redness, or hives and is typically triggered by foods or environmental allergens, swelling caused by vascular obstruction is generally painless, persistent, and not associated with rash or itching. For instance, Peter, a 70-year-old, noticed his face and neck becoming noticeably swollen every morning, with no other allergic symptoms. Emergency evaluation revealed a mass compressing his major veins.

The American Cancer Society urges that sudden or unexplained swelling of the face or neck should always be treated as a medical emergency. If this occurs, seek urgent care to rule out dangerous blockages or other serious underlying conditions.

45. Dizziness or Fainting

45. Dizziness or Fainting

Dizziness or fainting spells can be alarming symptoms and sometimes indicate complications of pancreatic cancer. Chronic illness may contribute to low blood pressure (hypotension) or anemia, both of which can reduce blood flow to the brain and trigger lightheadedness, unsteadiness, or even brief loss of consciousness. Tumor-related bleeding, poor nutrient absorption, or fluid shifts from advanced disease can all play a role.

While dehydration is a common and benign cause of dizziness—often resolved by drinking fluids—dizziness linked to anemia or hypotension from pancreatic dysfunction is persistent or recurrent and may not improve with hydration alone. For example, Evelyn, a 68-year-old, began feeling dizzy every time she stood up and even fainted once while cooking. Her symptoms persisted despite drinking plenty of water, and further evaluation revealed low hemoglobin levels from an undiagnosed pancreatic tumor.

According to the American Cancer Society, recurrent dizziness or fainting—especially with fatigue, paleness, or unexplained bleeding—should prompt immediate medical attention. Persistent lightheadedness may signal a serious underlying problem that warrants thorough investigation.

46. Difficulty Sleeping

Difficulty sleeping, or insomnia, is a common but often overlooked symptom in people with pancreatic cancer. Chronic pain, abdominal discomfort, and night sweats can make it hard to fall asleep or stay asleep. Additionally, metabolic and hormonal changes associated with cancer can disrupt the body’s natural sleep-wake cycles, resulting in restless nights and daytime fatigue.

Routine insomnia is typically linked to stress, anxiety, or changes in environment and often improves with relaxation techniques, sleep hygiene, or medication. However, sleep difficulties related to pancreatic disease may persist even with these interventions and are frequently accompanied by other symptoms such as unexplained pain, night sweats, or mood changes. For instance, Martha, a 66-year-old, noticed weeks of sleepless nights that didn’t improve with her usual remedies. This, combined with new digestive complaints, prompted her doctor to investigate further and discover her pancreatic condition.

According to the American Cancer Society, persistent difficulty sleeping—especially when new, severe, or associated with other health changes—should prompt further evaluation. Don’t ignore ongoing sleep issues, as they may be a sign of an underlying medical condition.

47. Mouth Sores

Mouth sores, or oral ulcers, can be a subtle sign of underlying pancreatic disease. When pancreatic dysfunction leads to malabsorption, the body may become deficient in essential nutrients such as B vitamins, iron, and folate—nutrients critical for healthy mucous membranes. This nutritional deficiency makes the mouth more susceptible to painful sores, cracks, or even swelling of the tongue.

Viral mouth ulcers, like those caused by herpes simplex, are usually short-lived and may be accompanied by fever or swollen lymph nodes. By contrast, mouth sores linked to malabsorption tend to last longer, recur frequently, and may resist conventional treatments. For example, Carla, a 64-year-old, developed persistent mouth ulcers and a burning sensation that didn’t improve with topical gels or antiviral medications. Bloodwork and further testing eventually revealed pancreatic insufficiency behind her nutritional deficits.

The Cancer Treatment Centers of America highlight that persistent or recurrent mouth sores, especially when accompanied by digestive issues or weight loss, should prompt assessment for malabsorption and underlying causes. Early intervention can help restore nutrition and address the root problem.

48. Frequent Nosebleeds

Frequent nosebleeds can sometimes signal underlying blood clotting issues, which may arise in people with pancreatic cancer. The pancreas indirectly influences clotting by affecting the liver’s ability to produce clotting factors and by contributing to malabsorption of vitamin K, an essential nutrient for blood clotting. As a result, individuals may experience recurrent episodes of spontaneous nosebleeds that are harder to stop than usual.

Most nosebleeds are benign and related to environmental factors such as dry air, allergies, or minor trauma (like nose picking). These typically resolve quickly and are not associated with other symptoms. However, when nosebleeds become frequent, difficult to control, or occur alongside other signs of bleeding—such as easy bruising or gum bleeding—they warrant further investigation. For example, Robert, a 67-year-old, noticed he was getting nosebleeds several times a week without any obvious cause. Lab tests later revealed impaired clotting due to pancreatic insufficiency.

The Cancer Treatment Centers of America stress that persistent or unexplained nosebleeds should always be evaluated by a healthcare provider, especially if accompanied by other bleeding symptoms or changes in overall health.

49. Swelling Around the Eyes

Swelling around the eyes, known as periorbital edema, can sometimes occur in people with pancreatic disease due to protein loss from malabsorption. When the pancreas is unable to produce or release enough digestive enzymes, the body struggles to absorb proteins efficiently. Low protein levels in the blood reduce oncotic pressure, allowing fluid to leak into soft tissues, with the delicate area around the eyes being especially prone to swelling.

This symptom can be mistaken for allergies or sinus issues, which also cause puffiness but are usually accompanied by redness, itching, or nasal congestion. Allergy-related swelling often fluctuates with exposure to triggers and improves with antihistamines. In contrast, periorbital edema from protein loss tends to persist or worsen over time and is not linked to environmental factors. For instance, Janet, a 70-year-old, noticed persistent puffiness around her eyes each morning that didn’t respond to allergy medications. Testing revealed low blood protein due to pancreatic enzyme insufficiency.

The Cancer Treatment Centers of America recommend evaluation for persistent or unexplained swelling around the eyes, particularly if accompanied by other symptoms of malnutrition or digestive issues. Early recognition can uncover underlying systemic problems that might otherwise go untreated.

50. Unusual Sensations in Hands or Feet

Unusual sensations such as tingling, numbness, or burning in the hands or feet—known as peripheral neuropathy—can sometimes be linked to pancreatic disease. Malabsorption caused by pancreatic insufficiency can lead to deficiencies in key vitamins (like B12, folate, and thiamine) that are crucial for nerve health. In some cases, pancreatic tumors themselves may secrete substances or trigger immune responses that damage nerves.

These symptoms are often mistaken for diabetic neuropathy, carpal tunnel syndrome, or even poor circulation. For example, Linda, a 68-year-old, noticed a persistent “pins and needles” feeling in her feet, even though she didn’t have diabetes or vascular problems. Further investigation revealed her neuropathy was due to vitamin deficiencies caused by pancreatic enzyme insufficiency.

The Cancer Treatment Centers of America recommend bringing persistent or unexplained tingling, numbness, or burning sensations to your doctor’s attention—especially if they develop alongside digestive changes, unexplained weight loss, or fatigue. Early evaluation can help pinpoint the underlying cause, ensure proper treatment, and prevent further nerve damage.
