Ovarian cancer is the fifth most common cause of
cancer death in women.1 It most often affects
postmenopausal women.
Women who have family members with ovarian cancer—especially
first-degree relatives such as a mother, sister, or daughter—who have had
ovarian cancer have a higher risk of getting it themselves.2
Women who are of Ashkenazi Jewish ancestry or Icelandic ethnicity may
have an increased risk because of changes to the
BRCA1 or BRCA2 genes. Women with this ancestry have
higher rates of these gene changes.3
Women who have had
breast cancer have twice the risk of developing
ovarian cancer compared to women who have not had breast cancer.3
Women who have a history of breast cancer in their family also have an
increased risk for ovarian cancer.
