Obese woman may face higher cancer risk

A new study by the Centers for Disease Control and Prevention suggests that obesity can significantly increase a woman's risk of developing endometrial cancer.The risk is even higher for women who have experienced early menopause.

The study, published in the July issue of Obstetrics and Gynecology, found that women who had their last menstrual cycle before the age of 45, and had a body-mass index (BMI) of 35 or greater, were 22 times more likely to have endometrial cancers than women who were not overweight. A BMI between 18.5 and 24.9 is considered normal by the CDC; anything over 30 is considered obese.

Researchers suspect that the increased risk is the result of a hormonal imbalance, specifically a lack of progesterone.
