Risks

Who is at risk?

Most causes of ovarian cancer occur for unknown reasons, but about 7% of ovarian cancers are thought to be caused by a faulty gene inherited from either parent. Researchers have also found that close relatives of women with ovarian cancer are slightly more likely to develop it themselves.

If you have a very strong family history you may be referred to a cancer geneticist. If increased risk is confirmed there may be the possibility of the prophylactic removal of your ovaries and tubes although this isn't 100% effective.

Am I at risk?

The incidence of the disease is largely confined to post menopausal women with 90% of cases occuring in the over 45s. It is more than twice as common in women who have never had children. There are some genetic links in a very small number of women, between 5-10% of cases. It may be more likely in women who have had endometriosis.

How can I reduce the risk?

Research carried out has shown that certain lifestyle choices can lower the risk of ovarian cancer:

• The combined oral contraceptive pill is protective and can half the risk in women who have used it for 3-5 years whereas there can be protection of up to 80% in long term users.
• breast feeding

There are some studies that suggest certain activities can increase risk, however there is considerable debate on the subject and some conflicting findings:

• Dairy consumption
• Taking HRT
• Talcum powder (Ovacome produces a factsheet that covers the link between talcum powder and ovarian cancer in more detail; click here to download (pdf).)
