Coffee may protect against womb cancer: Study

 In continuation of my update on the benefits of coffee
A new study shows that regular intake of coffee may significantly lower risk for endometrial or womb cancer.

For the study the researchers looked at coffee consumption and endometrial cancer risk in more than 67,000 women aged between 34 and 59 enrolled in the long-running Nurses' Health Study. The researchers found that women who took more than four cups of coffee a day over a 26-year period were 25 percent less likely to get the cancer. Women who drank two to three cups a day were 7 percent less likely to get it. Drinking less than four cups a day was not associated with reduced risk. Furthermore drinking tea did not reduce the risk. Additionally drinking more than two cups of decaffeinated coffee a day was tied to a 22 percent reduced risk for endometrial cancer.

The benefit wasn't a complete surprise, since coffee has been shown to lower estrogen and insulin levels, and higher levels of these hormones have been associated with an increased risk of endometrial cancer. But the new findings do help to clarify how obesity, estrogen and coffee might interact in triggering tumors.

“It would be premature to make a recommendation that women drink coffee to lower their endometrial cancer risk,” study author Dr. Edward Giovannucci, professor of nutrition and epidemiology at Harvard School of Public Health...
