Borderline ovarian tumors

Borderline ovarian tumors account for a small percentage of epithelial ovarian cancers. They are most often serous or mucinous cell types. They often have large masses, but they only rarely metastasize, that is, spread to other areas. Often, removal of the tumor, even at more advanced stages, can be a cure.

Germ cell ovarian cancers

Germ cells tumors arise from the reproductive cells of the ovary. These are uncommon. They include dysgerminomas, yolk sac tumors, embryonal carcinomas, polyembryomas, non-gestational choriocarcinomas, immature teratomas, and mixed germ cell tumors. They tend to occur more often in younger-aged women.

Stromal ovarian cancers

Another category of ovarian tumor is the sex cord-stromal tumors. These arise from supporting tissues within the ovary itself. As with germ cell tumors, these are uncommon. These cancers come from various types of cells within the ovary. They are much less common than the epithelial tumors. These include granulosa-stromal tumors and Sertoli-Leydig cell tumors.
