These are two different genetic tests, which look at different genes that play roles in cancer risk and drug metabolism, respectively. The test you took, often called the BRCA test, tells you about an inherited risk for developing breast and ovarian cancer. The tamoxifen 2D6 test tells you about whether or not tamoxifen will be an effective treatment for preventing breast cancer recurrence. Genetic testing for hereditary breast and ovarian cancer checks for mutations in the BRCA1 and BRCA2 genes that are known to be associated with breast and ovarian cancer. This test is appropriate for women whose personal and/or family history places them at high risk for these cancers. This test can provide valuable information to help take preventive action, start high-risk screening practices, and provide relatives with additional information about their risk. The tamoxifen 2D6 test, by contrast, is a drug metabolism test. This test tells whether the breast cancer, drug tamoxifen is likely to be a
