Breast cancer is one of the leading causes of death in the U.S. Earlier research has linked genetics, hormones, stress and environmental toxins to the risk of breast cancer. The new study shows that a strong factor contributing to the cancer might be lurking in a Big Mac or even that tempting piece of cake.
Previous research has shown that high-fat diet is linked with an increased breast cancer risk. However, nobody knew how fat posed a threat. Now, researchers have found the cholesterol metabolite that mimics the hormone estrogen. The study may also explain why cholesterol-lowering drugs such as statins help reduce breast cancer risk.
