The ovary is a small organ in women that makes female hormones (estrogen and progesterone) and holds egg cells.
There are two ovaries: one located on the left side of the uterus (the hollow, pear-shaped organ where a baby can develop) and one located on the right.
Cancer of the ovary is a disease in which cancer cells grow in the ovary. Most commonly, the cancer begins in the lining (epithelium) of the ovary and is called germ cell tumor.
