Quick facts about ovarian cancer

  • Over 7,000 women are diagnosed each year in the UK

  • Anyone with ovaries can get ovarian cancer, so it mostly affects women. Transgender men and intersex people can also get ovarian cancer if they have ovaries.

Types of ovarian cancer

Ovarian cancer can be one of three types:

  • Epithelial ovarian cancer

    This can involve either one or both ovaries, where cancer cells grow on the outside of the ovary. This type of ovarian cancer is the most common form, accounting for approximately 90% of ovarian cancers.

  • Germ cell ovarian cancer

    This involves the cells that produce the eggs and accounts for approximately 4% of all ovarian cancers.

  • Stromal tumour ovarian cancer

    This involves the tissues that support the ovary in producing oestrogen and progesterone hormones. This type of ovarian cancer is very rare.

Signs and symptoms of ovarian cancer

Discussing anything concerning with your doctor as soon as possible can help give you peace of mind and offer the best chance of successful treatment if you receive an ovarian cancer diagnosis.

Bloating or an extended abdomen

Stages of ovarian cancer

Ovarian cancer is typically staged using the FIGO (International Federation of Gynaecology and Obstetrics) system, which helps doctors understand what your cancer looks like.

Within each stage of ovarian cancer, there are sub-stages listed from A through to D which describe the extent of the tumour.

The FIGO system, along with other tests, helps determine the stage of your ovarian cancer using the guidelines below:

  • Stage I

    Cancer has been found in either one or both ovaries.

  • Stage IV
