Causes
Main causes of ovarian cancer
The risk of developing ovarian cancer increases with age, with more than half of all cases in the UK in women aged 65 and over.
Anyone with ovaries can get ovarian cancer.
You may have a higher chance of getting ovarian cancer if you:
- inherited a faulty gene, such as the BRCA genes or those linked to Lynch syndrome
- had breast cancer or bowel cancer
- had radiotherapy treatment for a previous cancer
- have endometriosis or diabetes
- started your periods at a young age or went through the menopause late (over 55), or have not had a baby – because these things may mean you’ve released more eggs (ovulated more)
- have never used any hormonal contraception, such as the pill or an implant
- are taking hormone replacement therapy (HRT)
- are overweight
- smoke
It's still possible to get ovarian cancer even if you've had your ovaries removed. This is because ovarian cancer can also affect your fallopian tubes, or the lining inside your tummy (peritoneum).
