If a family member has ovarian cancer, can genetic screening determine if other family members will get the disease?

Yes: Ovarian cancer, especially pre-menopausal ovarian cancer is a rare disease and i recommend family members of such patients atleast have a genetics consultation to talk about testing. Brca-1 and brca-2 mutations put women at a much higher risk of developing ovarian, breast and endometrial cancers. More common in jewish women. Hnpcc (lynch syndrome) also increases the risks of female cancers.

The BRCA: Family type i & ii are associated with not only ovary bit breast cancer, and screening alllows your family to make decisions about their breasts and ovaries before cancer develops.
