Women who exercise for at least two and a half hours each week may be able to reduce their risk of developing endometrial cancer, researchers from Yale University indicate.

Endometrial cancer is just one of the many uterine cancers, and is specifically associated with that develops in the uterus.

The scientists analyzed the data of more than 668 women who had been diagnosed with this form of cancer. These participants were then compared to 665 healthy controls. All of the subjects were similar in their age.

Overall, the women who exercised for at least 150 minutes or more each week,experienced a 34 percent reduced risk of developing endometrial cancer when compared to those who were inactive.

Weight was not considered to affect the outcome, as both normal and overweight subjects were able to lower their risk of having endometrial cancer.

Hannah Arem, one of the study’s authors, said that because of these results, “programs should be in place to increase the level of physical activity in women.”

According to the National Cancer Institute, there will be approximately 43,470 newly diagnosed cases of endometrial cancer in a given year in the U.S.
