Mutations: The brca test can identify carriers of the mutations associated with the hereditary type of breast (& ovarian) cancer. Depending on the mutation (and sex of the patient) there are different risks of these cancers--this is best discussed w/a genetic counselor. One can then decide to have preventive surgery (mastectomy, oophorectomy), take risk-reducing medication, or close surveillance.

Mutation=cancer risk: People with mutations in the brca1 or brca2 gene are at higher risk of developing certain cancers. With a mutation, the lifetime risk of breast cancer is 41 to 90%, and ovarian cancer is 8 to 62%. Pancreatic and prostate cancer are more common as well. If you are a woman and test positive, you will have to consider having your ovaries and breasts removed. Genetic counseling is key!
