A woman diagnosed with fallopian tube cancer, ovarian cancer, uterine cancer, primary peritoneal cancer should undergo genetic testing. About 15% of patients diagnosed with ovarian cancer have a change in mutation or change in the BRCA gene. About 3% to 5% of women with uterine cancer have Lynch Syndrome- inherited cancer syndrome.
Cancers caused by a gene mutation need a different plan of treatment, your health care unit asks your relatives blood samples and their cancer history to treat you. Some family members have to undergo genetic testing for genetic counseling.
