What is ovarian cancer?

The term "ovarian cancer" includes several different types of cancer that all arise from cells of the ovary. Most commonly, tumors arise from the epithelium, or lining cells, of the ovary. These include epithelial ovarian (from the cells on the surface of the ovary), fallopian tube, and primary peritoneal (the lining inside the abdomen that coats many abdominal structures) cancer. These are all considered to be one disease process. There is also an entity called borderline ovarian tumors that have the microscopic appearance of a cancer, but tend not to spread much.

However, there are also less common forms of ovarian cancer that come from within the ovary itself, including germ cell tumors and sex cord-stromal tumors. All of these diseases will be discussed, as well as their treatment.

Epithelial ovarian cancer

Epithelial ovarian cancer (EOC) accounts for about 70% of all ovarian cancers. It is generally thought of as one of three types of cancer that include ovarian, fallopian tube, and primary peritoneal cancer that all behave, and are treated the same way, depending on the type of cell that causes the cancer. The four most common cell types of epithelial ovarian cancer are serous, mucinous, clear cell, and endometrioid. These cancers arise due to DNA changes in cells that lead to the development of cancer. Serous cell type is the most common variety. It is now thought that many of these cancers actually come from the lining in the fallopian tube, and fewer of them from the lining on the surface of the ovary, or the peritoneum. However, it is often hard to identify the sources of these cancers when they present at advanced stages, which is very common.
