Types of ovarian cancer

Epithelial ovarian cancer is the most common type of ovarian cancer. Primary peritoneal cancer and fallopian tube cancer are similar to epithelial ovarian cancer and are treated in the same way.

Germ cell ovarian tumours begin in the ovarian cells that develop into eggs. They can be non cancerous (benign) or cancerous (malignant).

Sex cord stromal ovarian tumours can be non cancerous (benign) or cancerous (malignant). Granulosa cell tumours are the most common type.

Borderline ovarian tumours are abnormal cells that form in the tissue covering the ovary. They are not cancer and are usually cured with surgery.
