Researchers from the Keck School of Medicine at the University of Southern California say that women who have more than two alcoholic drinks daily face twice the risk of endometrial cancer as those who drink moderately or not at all, the New York Times reported Sept. 18.

Endometrial cancer affects the tissue linking the uterus. It kills about 7,400 women in the U.S. annually.

Researchers drew their conclusions from a study of more than 41,000 women, controlling for variables like body-mass index, age, pregnancy history, and use of hormone therapy.

"Relatively few studies have examined the relationship between endometrial cancer and drinking," said lead researcher Veronica Wendy Setiawan. "If this is a true association, that's one more lifestyle change women can make."

The study appears online in the International Journal of Cancer.
