The BRCA1, 2 test is a genetic test used to detect mutations in the BRCA1 and BRCA2 genes. These genes play an important role in suppressing tumor growth. When there are mutations in these genes, the risk of breast cancer, ovarian cancer, and several other types of cancer increases. This test is usually indicated for people with a family history of breast cancer, ovarian cancer, or cancers related to the BRCA1 and BRCA2 genes. The test results will help the doctor assess cancer risk and provide appropriate prevention or treatment methods.
