How does a BRCA1 or BRCA2 gene mutation affect my risk of cancer?

If you have a defect (mutation) in the BRCA1 or BRCA2 gene, it means that you may have an 18 to 62 percent chance of getting ovarian cancer.

Everyone has the BRCA genes. They are designed to help prevent the overproduction of cells. Only about 10 percent of women with ovarian cancer have a mutation in one or both of these genes.

If you have a history of ovarian cancer in your family, you can seek the help of a qualified genetic counselor to conduct an extensive genetic/medical history and obtain advice about whether or not to proceed with the test. If either of these genes is defective, it doesn't mean you'll get cancer. Plus, you can take preventive steps such as having your ovaries removed to significantly reduce your risk. Seek advice from your healthcare professional on how to proceed.
