A report in JAMA today ( http://jama.ama-assn.org/content/306/17/1884.abstract?ijkey=d518a6cf2673dc22cb9393c553a884d58f02967b&keytype2=tf_ipsecsha) correlating moderate alcohol consumption and breast cancer incidence seems to suggest that abstinence from alcohol might have the effect of reducing your risk of breast cancer. Indeed, from some of the interviews (e.g. http://vitals.msnbc.msn.com/_news/2011/11/01/8585033-even-light-drinking-slightly-ups-breast-cancer-risk) there's a hint that alcohol may induce or amplify estrogenic effects on breast cancer. The question in your mind should be, is this good science, and should I be listening to it?
