Postmenopausal women consuming two or more alcoholic beverages a day may double their risk of endometrial cancer, suggests a study led by researchers at the University of Southern California (USC).
According to the National Cancer Institute, endometrial cancer is the most common cancer of the female reproductive system. It accounts for approximately six percent of all cancers in women.
This is the first prospective study to report a significant association between alcohol and endometrial cancer . Previous studies have shown that alcohol consumption has been associated with higher levels of estrogens in postmenopausal women, which could be the mechanism by which daily alcohol intake increases oneâ€™s risk of endometrial cancer.
The study also found that the association of alcohol intake and endometrial cancer is stronger among lean women than among overweight or obese postmenopausal women.
This discovery is important as it suggests that changes to certain lifestyle choices may potentially help alter risk of the disease, However, these findings are preliminary and must be investigated further before any recommendations about alcohol consumption can be made.
