What is Ovarian Cancer?

Ovarian cancer begins when cells grow out of control in the ovaries, which produce eggs, and the hormones estrogen and progesterone. It’s most common in post-menopausal women; in Minnesota, over 80% of cases are in women over 50. Symptoms of ovarian cancer are often vague, and because of this, it may go undetected until the later stages. By then, it may spread, or metastasize, to other areas of the pelvis or abdomen.

There are more than 30 different types of ovarian cancer; they’re identified based on the name of the cell in which the cancer originated.

  • Epithelial. These tumors develop in the layer of tissue on the outside of the ovaries.
  • Stromal. These tumors grow in hormone-producing cells.
  • Germ cell. These tumors develop in egg-producing cells.


Ovarian tumors develop most commonly in the epithelial cells in the outer layer of the ovary. Although most of this type are benign, cancerous epithelial tumors account for 85% to 90% of ovarian cancers and often spread elsewhere. Stromal tumors represent only about 5 percent of ovarian tumors, while germ cell tumors are even rarer.

Primary peritoneal carcinoma and fallopian tube cancer are similar to epithelial ovarian cancer and are often treated with the same techniques. Long term survival rates for these cancers vary widely, depending on the type and stage of cancer, and a woman’s ethnicity.
