Ovarian cancer can be divided into 3 major categories based on the type of cell from which it arises. This includes :
- Epithelial carcinoma
- Germ cell carcinoma
- Sex cord and stromal carcinoma
These are primary carcinomas of the ovary, which originate in the ovary itself.
The other type of carcinoma that may be found in the ovary is known as secondary or metastatic carcinoma. Here, the primary cancer is elsewhere in the body but it has metastasized to the ovary.
