Mutations in either breast cancer gene — BRCA1 or BRCA2 — significantly increase the risk of: 1. Breast cancer 2. Male breast cancer 3. Ovarian cancer 4. Prostate cancer 5. Pancreatic cancer 6. Melanoma If a gene mutation is detected, you …
Risks
- There's no medical risk associated with being tested for a BRCA gene mutation other than the slight risks — including lightheadedness, bleeding or bruising — of having your blood drawn. Other consequences surrounding genetic testing include the emotional, financial, medical and social implications of your test results. If you test positive for an inherited genetic mutation, you may f…
How You Prepare
- The first step in the BRCA gene testing process is to meet with a genetic counselor. As soon as you consider having any genetic test, meet with a genetic counselor to determine whether it's appropriate for you and to discuss the potential risks, limitations and benefits of undergoing genetic testing. The genetic counselor takes a detailed family and medical history, assesses you…
