Genetic Testing
Discuss your family history with your doctor. Tell your doctor about any previous cancers you have had such as breast or colon cancer. If you have one or more first-degree relatives (mother or sister) who have had ovarian cancer, this suggests a possible hereditary cause. If you are at high risk for ovarian cancer, your doctor will recommend additional testing, which may include genetic testing.

Blood tests are available for the BRCA1 or BRCA2 genes, which also cause breast cancer, and for genes involved in a familial colon cancer syndrome called Lynch syndrome. In a woman believed to be at high risk for carrying one of these mutations, a blood test may help determine whether she is at high risk for the development of ovarian cancer (as well as breast, uterine, or colon cancer, depending on the gene). Many women find this information helpful in making important decisions about certain prevention strategies for them and their children. There are benefits and risks with genetic testing, so women should discuss them with their doctor.
