What is ovarian cancer?
Ovarian cancer develops in the ovaries, which are the female reproductive glands that produce eggs during a woman's reproductive years. The ovaries also produce the hormones estrogen and progesterone. Ovarian cancer develops when cells in the ovaries begin to grow out of control.
Ovarian cancer incidence
The American Cancer Society estimates that 22,240 new cases of ovarian cancer will be diagnosed in the United States in 2018. Although relatively rare—this cancer accounts for about 2.5 percent of all cancers in women—it’s the fifth leading cause of cancer-related deaths among women in the United States.
