How can I prevent ovarian cancer?

Some women have genes that increase the risk of ovarian cancer. These genes are called BRCA1 and BRCA2. They also increase the risk of breast cancer. If you have family members who've had breast or ovarian cancer, you should talk to your doctor about gene testing. If you have one of these genes, having your ovaries removed may help prevent cancer.
