Reducing Risks

The actual cause of ovarian cancer are not known. Some factors seem to put women at a higher risk of developing ovarian cancer. Many women who develop ovarian cancer however, do not have these risk factors. At the same time many women who do have the risk factors do not develop ovarian cancer.

• Ovarian cancer is more common in Caucasian (white) women who live in westernized countries with a high standard of living.
• Women who have had no or few full term pregnancies appear to be more at risk of ovarian cancer.
• Women who have never been on the contraceptive pill also seem to be more at risk. The exact reason is uncertain. It could be because the ovaries have never had a 'rest' from ovulation during women's lifetime.
• Some types of ovarian cancer may be linked with a family history of cancers of the ovary, bowel, breast and lining of the uterus.

Other factors may increase your risk of developing the disease:

• You have a personal medical history of multiple exposures to fertility drugs
• You are of Ashkenazi Jewish descent
• A high fat diet and being overweight
• You have had genital contact with talcum or asbestos, which are sometimes used in douches and condoms (highly controversial and unproven)

If you are at increased risk, ensure your doctor knows of the relevant medical or family history.

Young women in their teens, early twenties, and older women have all been known to be diagnosed with ovarian cancer. Although ovarian cancer is curable if diagnosed early, it remains the most lethal gynaecologic cancer because it is so difficult to detect.

Research into the causes of ovarian cancer is continuing in Australia and overseas.
