There are 3 types of ovarian cancer :

  1. Epithelial tumors

  2. Stromal tumors

  3. Germ cell tumors

Epithelial Tumor
Epithelial ovarian tumors develop from the cells that cover the outer surface of the ovary. Most epithelial ovarian tumors are benign (noncancerous). There are several types of benign epithelial tumors, including serous adenomas, mucinous adenomas, and Brenner tumors. Cancerous epithelial tumors are carcinomas - meaning they begin in the tissue that lines the ovaries. These are the most common and most dangerous of all types of ovarian cancers.

Stromal Tumor
Ovarian stromal tumors are a rare class of tumors that develop from connective tissue cells that hold the ovary together and those that produce the female hormones, estrogen and progesterone and also in the stroma of ovary. The most common types are granulosa-theca tumors and Sertoli-Leydig cell tumors.

Germ Cell Tumor
An ovarian germ cell tumor is growth in a woman's ovaries. Most aren’t cancer. Instead, they are “benign” growths. Cancerous germ cell tumors are rare.Germ cell tumors start in the ovarian cells that produce eggs.
