The job of these hormones is to regulate the menstrual cycle/menstruation. Ovaries also include eggs which are regulated by the hormones during the cycle. Once an ovarian cell becomes cancerous, it will begin to multiply itself and spread quite rapidly. A tumor on the ovary is created when the cells multiply. It is possible for the tumor to interfere with the functions of the ovary. It can also spread to other areas inside the pelvis by breaking itself off and infecting that area. The cancer cells themselves can also spread by traveling through the bloodstream and therefore infecting several other body parts.

The second type of tumors that can develop are called Germ Cell Tumors. The account for 3% of ovarian cancer cases and are found in the egg making cells of the ovary. They are found mostly in teenagers and young women. They spread rapidly as well, but are quite weak and are treatments ...
