Typically, for ovarian cancer, we're usually asking women who have that cancer history with family members to go ahead and remove Fallopian tubes and ovaries at a minimum of about 10 years before an incidental cancer in their family or as soon as they are done child-bearing. The reason we say this is that ovarian cancer is so difficult to treat. You do not want to miss an opportunity to intercede and remove those cancers.
Endometrial cancer is also another cancer that can be genetically related through Lynch syndrome. People don't realize how strong a connection that is. About 80% of Lynch syndrome family members can get endometrial cancer. Most people associate it with colon cancer, but the connection is actually just as strong for endometrial cancer.
