Ovarian cancer is cancer that begins in the ovaries. The ovaries make female hormones and produce a woman’s eggs. Ovarian cancer is a serious cancer that is more common in older women. Ovarian cancer ranks fifth in cancer deaths among women, accounting for more deaths than any other cancer of the female reproductive system. A woman's risk of getting ovarian cancer during her lifetime is about 1 in 75. About half of the women who are diagnosed with ovarian cancer are 63 years or older. It is more common in white women than African-American women. The rate at which women are diagnosed with ovarian cancer has been slowly falling over the past 20 years. Treatment is most effective when the cancer is found early. For more information, click on the links below.
