Having diabetes is associated with an increased risk of endometrial cancer.
The risk of endometrial cancer increases by at least 30% in women who have diabetes compared with those who do not.
It has been estimated that almost 11% of cases worldwide of endometrial cancer are due to women having diabetes.
Most people with diabetes have 'type 2' diabetes, which is associated with higher body fatness. Being overweight or obese may contribute to the increased risk of endometrial cancer in women with diabetes.
The increased risk of endometrial cancer in women with diabetes is likely to be due to hormones. People with diabetes have lower levels of the hormone insulin. This can result in higher levels of the female hormone oestrogen which can increase the risk of endometrial cancer.
