Definition
By Mayo Clinic staffOvarian cancer is a type of cancer that begins in the ovaries. Women have two ovaries, one on each side of the uterus. The ovaries — each about the size of an almond — produce eggs (ova) as well as the hormones estrogen, progesterone and testosterone.
Ovarian cancer often goes undetected until it has spread within the pelvis and abdomen. At this late stage, ovarian cancer is difficult to treat and is often fatal.
Ovarian cancer treatments are available. Researchers are studying ways to improve ovarian cancer treatment and looking into ways to detect ovarian cancer at an earlier stage — when a cure is more likely.
