WASHINGTON, Nov. 22 (Xinhua) -- Long-term coffee consumption may be associated with a reduced risk for endometrial cancer, according to a study published online Tuesday in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
Edward Giovannucci, professor of nutrition and epidemiology at the Harvard School of Public Health, said that coffee is emerging as a protective agent in cancers that are linked to obesity 1, estrogen and insulin.
"Coffee has already been shown to be protective against diabetes 2 due to its effect on insulin," said Giovannucci, a senior researcher on the study. "So we hypothesized that we'd see a reduction in some cancers as well."
The researchers observed cumulative 3 coffee intake 4 in relation to endometrial cancer in 67,470 women who enrolled 5 in the Nurses' Health Study. During the course of 26 years of follow-up, researchers documented 672 cases of endometrial cancer.
Drinking more than four cups of coffee per day was linked with a 25 percent reduced risk for endometrial cancer. Drinking between two and three cups per day was linked with a seven percent reduced risk.
A similar link was seen in decaffeinated coffee, where drinking more than two cups per day was linked with a 22 percent reduced risk for endometrial cancer.
Giovannucci said that he hopes this study will lead to further inquiries 6 about the effect of coffee on cancer because in this and similar studies, coffee intake is self-selected and not randomized.
