(CollegiateTimes) - Women may now have something to think about before they toast their next glass of red wine. Drinking four glasses of red wine per week could increase a woman’s chances of developing breast cancer, according to findings from a recent study conducted at Harvard University. The study’s findings are based the results of a survey given to more than 100,000 nurses who answered questionnaires about their health habits and alcohol consumption from 1980 until 2008. It found that women who drink red wine have a 15 percent increased risk of being diagnosed with breast cancer.
