The higher the body mass index of a women, the higher are also her odds to get a cancer of the uterus, called endometrial cancer. Source: A big European Study. It seems to be clear what a woman has to do against it: Eat less, stay slim or lose her fat. But this is far from easy.
Fortunately, there is another way that may help to lower this cancer risk: Take the pill. Oral contraception may attenuate the cancer-promoting effect of too much body fat to a certain extent. But nothing is for nothing. The pill may raise cancer risk in other locations of the body such as cervix or breast. - (Picture by Beddoes @ Flickr)
