Losing weight as a result of dieting or surgery by women who are obese may be associated with a decreased risk of endometrial cancer.
It is estimated that at least one-quarter of cases of endometrial cancer in Australia could be prevented if all women had a healthy weight.*
Increasing body fatness in adult women increases the risk of endometrial cancer. People who are obese have higher levels of the female hormone oestrogen, which can increase the risk of endometrial cancer. They may also have higher levels of certain proteins and other factors in their blood caused by inflammation, which may increase the risk of endometrial cancer. Weight loss is likely to reduce levels of these hormones and proteins, decreasing the risk of endometrial cancer.
