Endometrial Cancer Prevention

Exercising 150 minutes or more every week may reduce risk for endometrial cancer.
The Los Angeles Times (11/9, Stein, Times) "Booster Shots" blog reported that the majority of adults are urged to get at least "150 minutes" of exercise each week. Now, Yale researchers suggest that level of physical activity "or more may decrease a woman's risk of endometrial cancer."
Before reaching that conclusion, investigators "looked at data on 1,333 women -- 668 with endometrial cancer from the population-based Rapid Case Ascertainment Shared Resource at the Yale Cancer Center and 665 age-matched controls," MedPage Today (11/9, Neale) reported. "After controlling for potential confounders, including BMI and age, active women (those who participated in more than the equivalent of 7.5 MET hours/week) had a 34% reduced likelihood of endometrial cancer compared with those who were inactive." And, even though the "odds reduction occurred in both normal-weight and overweight women, it was greatest in normal-weight women who were active compared with overweight women who were inactive (OR 0.27, 95% CI 0.19 to 0.38)."
