The test for alterations (mutations) in the BRCA2 gene and accompanying genetic counseling are recommended only for women who are at high risk for breast cancer and ovarian cancer due to a strong family history of breast cancer or ovarian cancer.[1]
Tests for altered BRCA1 and/or BRCA2 genes are performed on a blood sample that is drawn in a doctor's office, clinic, laboratory, or hospital. Then the blood sample is sent to a special laboratory to check for mutations in the BRCA1 and/or BRCA2 genes.
