Ovarian Cancer

Ovarian cancer begins in the ovaries, which are located on each side of the uterus and produce female hormones and eggs. Some tumors located next to ovarian tissues are considered ovarian cancer, such as cancer of the membrane lining the walls of the pelvic cavity next to the ovaries.

There are three common types of ovarian cancer:

  • Epithelial tumors arise from cells that line or cover the ovaries.
  • Germ cell tumors originate from cells that form eggs.
  • Sex cord-stromal cell tumors begin in the connective cells that hold the ovaries together and produce female hormones.
