BRCA1 and BRCA2 tests are genetic tests in which samples of a patient’s blood can be used to determine that person’s risk for developing breast and ovarian cancer. While a mutation in a person’s BRCA1 or BRCA2 genes indicates an elevated risk of a hereditary form of breast and/or ovarian cancer, it’s important that anyone undergoing this kind of test receive expert counseling both before and after the procedure so you understand what the results actually mean to you. Your doctor can also tell you about available options for mitigating your cancer risk when a mutation is found in the BRCA1 or BRCA2 genes, including risk-reducing surgeries and other treatments.
