Family History of Breast Cancer
Your risk of developing breast cancer may be higher if a close relative, such as a mother, sister, or daughter, has had breast cancer at a young age. In such cases, it might be advisable to consider genetic testing to assess your genetic risk factors. Genetic testing is a straightforward process, typically involving a blood test that is often covered by most insurance companies. While the testing itself is relatively simple, the decision to undergo genetic testing is significant and requires careful consideration. It’s essential to weigh the potential implications of the test results on various aspects of your life, including your health, career, and family.
Starting with genetic counseling is a wise step for anyone who suspects they might carry a gene that increases the risk of cancer. This process can help you understand the significance of genetic testing and its potential impact on your well-being and family members. Guidelines for who should undergo genetic testing may evolve over time. Typically, your doctor may recommend it if a close family member has tested positive for carrying a mutated gene, you have a family history of breast or ovarian cancer, you were diagnosed with breast cancer at a young age, or other specific factors apply, such as Ashkenazi Jewish ancestry or multiple cases of breast cancer within your family.
Genetic testing may begin with a family member already diagnosed with breast or ovarian cancer, and if they test positive for a mutation, other family members can be tested to determine their risk. However, if no one in the family carries the mutation, the test is considered non-informative and cannot identify at-risk family members.
