What are the types of ovarian cancer?
Most forms of ovarian cancer begin in the surface epithelial cells, which cover the surface of the ovaries. They often start at the part of the ovary near the end of the fallopian tube.
Other, less common types of ovarian cancer may form in:
- Germ cells. These cells ultimately form the eggs.
- Stromal cells. These cells release the hormones estrogen and progesterone and help hold the ovary together.
