From Mamm Mag " Alcohol is a known risk factor for breast cancer. Now scientists at the U of Mississippi may be able to explain the link. They created a laboratory mouse model that mimics the development of alcohol-induced breast cancer in humans. Scientists found that even moderate alcohol consumption--the equivalent of two drinks per day in humans--nearly doubles the size of breast tumors in mice. They also found an increase in blood vessel density and specific proteins that cause tumor growth. "
