Forget fitting into smaller jeans—slimming down can save your life.
Overweight women have four times the endometrial cancer risk, probably for the same reason they’re at increased risk for breast cancer: Body fat produces estrogen, a hormone linked to both diseases, says a recent study at the University of Texas M.D. Anderson Cancer Center in Houston. Likewise, University of Minnesota researchers found that leptin, a hormone associated with weight gain, enhanced the proliferation of both normal and cancerous breast cells.
Make one change: Talk with your doctor about birth-control pills. Women who take a pill containing both estrogen and progestin have a 50 percent lower risk of developing endometrial cancer.
