Ovarian cancer can now be considered another of the many risks of obesity.

The U.S. National Cancer Institute followed women ages 50-71 for an average of seven years and found obese, postmenopausal women, who have never used hormone replacement therapy, face an increased risk of ovarian cancer compared to normal weight women.

Researchers believe the excess weight triggers more estrogen production, which in Turn increases the odds for hormone-related disease, including both breast and ovarian cancers.
