- Ovarian cancer involves abnormal cell growth within the ovary and surrounding tissues
- Ovarian cancer can be one of three types:
- Epithelial– which can involve either one or both ovaries, where cancer cells grow on the outside of the ovary.
- In some occasions, the cancer will be growing along the lining of the abdomen (peritoneal lining).
- This type of ovarian cancer is the most common, accounting for approximately 90% of ovarian cancers.
- Germ cell – involves the cells that produce the eggs, and account for approximately 4% of all ovarian cancers.
- Stromal tumour – involves the tissues that support the ovary in producing oestrogen and progesterone hormones.
