What are the types of ovarian cancer?

Epithelial cancers
The cancer is found on the surface of the ovary, rather than inside the ovary. Epithelial cancer is further divided into different types: High-grade serous, low-grade serous, mucinous, endometriod, clear cell and undifferentiated.

Non-epithelial cancers
These include germ cell tumours and stromal cell tumours. Germ cell tumours start in the part of the ovary that produces eggs and tend to affect very young women. Stromal tumours affect the tissues that support and keep the ovary in place and are extremely rare.

Borderline tumours
Borderline tumours have cells that are similar to the normal cells in your ovary. They are classed as tumours of low malignant potential. This means that most of these tumours are not a cancer and can be treated by surgery. However, in some cases they can recur and have the ability to transform into cancer. They are generally diagnosed at an early stage.

Ask your doctor if you want more information about your cancer type and what it means for you and your treatment.
