Question: Is Ovarian Epithelial, Fallopian Tube, and Primary Peritoneal Cancer inherited ?
Answer: Some ovarian, fallopian tube, and primary peritoneal cancers are caused by inherited gene mutations (changes). The genes in cells carry the hereditary information that is received from a persons parents. Hereditary ovarian cancer makes up about 20% of all cases of ovarian cancer. There are three hereditary patterns: ovarian cancer alone, ovarian and breast cancers, and ovarian and colon cancers. Fallopian tube cancer and peritoneal cancer may also be caused by certain inherited gene mutations. There are tests that can detect gene mutations. These genetic tests are sometimes done for members of families with a high risk of cancer. See the following PDQ summaries for more information: - Ovarian, Fallopian Tube, and Primary Peritoneal Cancer Prevention - Genetics of Breast and Gynecologic Cancers (for health professionals)

Question: How to prevent Ovarian Epithelial, Fallopian Tube, and Primary Peritoneal Cancer ?
Answer: Women with an increased risk of ovarian cancer may consider surgery to lessen the risk. Some women who have an increased risk of ovarian cancer may choose to have a risk-reducing oophorectomy (the removal of healthy ovaries so that cancer cannot grow in them). In high-risk women, this procedure has been shown to greatly decrease the risk of ovarian cancer. (See the PDQ summary on Ovarian, Fallopian Tube, and Primary Peritoneal Cancer Prevention for more information.)
