Drinking coffee may cut the chances a woman will develop endometrial cancer, in findings that come from Harvard School of Public Health researchers. Drinking more than 4 cups a day was linked to a 25 percent reduction in endometrial cancer cases in an analysis that included 67,470 women enrolled in the Nurses’ Health Study.

In the study that spanned 26 years, women who drank less than 4 cups of coffee a day had a 7 percent lower risk of endometrial cancer

Edward Giovannucci, M.D., Sc.D., professor of nutrition and epidemiology at the Harvard School of Public Health and senior researchers on the study said coffee explains coffee seems to protect from a variety of cancers that are linked to obesity, estrogen and insulin resistance.

In the study, published in the journal Cancer Epidemiology, Biomarkers & Prevention, the researchers found 672 cases of endometrial cancer among the 67, 470 women. From their analysis, they found both caffeinated and decaffeinated coffee was linked to reduced risk of the cancer.

Women who drank between two and three cups per day appeared to have a 7 percent reduced risk of endometrial cancer.

“Coffee has already been shown to be protective against diabetes due to its effect on insulin,” said Giovannucci, “So we hypothesized that we’d see a reduction in some cancers as well.”

The same risk was seen in decaffeinated coffee. More than two cups per day was linked with a 22 percent reduced risk for endometrial cancer.

According to the National Cancer Institute, there were 46,470 new cases of the disease in 2011 that claimed 8,120 lives.

Giovannucci warns that drinking coffee and having a cigarette would reverse the positive effect on reducing endometrial cancer risk from the beverage. There is also some evidence that coffee might slightly raise the risk of breast disease in young women that could lead to breast cancer.

He also notes coffee has more antioxidants in coffee than most fruits and vegetables, making it a healthy beverage choice for most people. The finding showed 2 to 4 cups of coffee a day, regular or decaf, might protect women from endometrial cancer.

Coffee also increase the risk of heart attack, stroke and blood clots.
I don't think there is evidence to show that's true, especially regarding blood clots. If anything, coffee, from what we currently know, may prevent blood clots. http://www.ncbi.nlm.nih.gov/pubmed/18439332
