Ovarian Cancer

What is ovarian cancer?

The female reproductive system contains two ovaries on each side of the uterus. The ovaries are where eggs are developed. Ovarian cancer occurs when malignant cell growth affects parts of the ovaries.

What are the different types of ovarian cancer?

There are different types of ovarian cancer classified by the type of cell from which it originates:

• Epithelial ovarian cancer is the most common type of ovarian cancer. It develops from a type of cell that surrounds the exterior of the ovaries.
  
• Germ cell ovarian cancer develops from germ cells that make the eggs.
• Stromal ovarian cancer develops from connective tissue cells that fill the ovaries.
