I have already been diagnosed with breast cancer. Is genetic testing still worthwhile for me?

Genetic test results can provide information that affects treatment choices and follow-up care for breast cancer patients and survivors. Further, if a cancer survivor is the first person to have a genetic test in a family, that test result may help identify the cause of hereditary cancer in a family. This information can help other family members make decisions about genetic counseling and testing.
