What is ovarian cancer?
Ovarian cancer begins in the ovaries, which are two almond-shaped glands located on either side of the uterus. The ovaries produce the female hormones, estrogen and progesterone, and release eggs during a woman’s reproductive years (the time from her first menstrual period through menopause).
Ovarian cancer incidence
The American Cancer Society estimates there will be 21,290 new cases of ovarian cancer diagnosed in the United States in 2015. Ovarian cancer is relatively rare. It is the seventeenth most common cancer in women, according to the National Cancer Institute.
