Just One Glass of Wine a Day Increases Your Risk of Breast Cancer

I apologize ahead of time for this Friday morning buzzkill, but you should probably know — consuming just one alcoholic drink a day can increase your risk of breast cancer.

New findings published in The Journal of the National Cancer Institute indicate that compared with not drinking, consuming 10 grams of alcohol six times a week (a usual drink contains about 14 grams of alcohol) was associated with an 11 percent increase in breast cancer and a 16 percent increase in B.B.D. (benign breast disease).

If you’ve never carried a pregnancy to term, the risk is even higher. Scientists believe this is because breast tissue in women who have never  been pregnant is more susceptible to carcinogens.

“Limiting alcohol can pay off through reduced breast cancer risk,” explained Dr. Graham A. Colditz, a co-author of the study and professor of surgery at Washington University in St. Louis. “This interval in adolescence and young adulthood is extremely important for setting the lifetime risk for breast cancer.” Bummer.

On the positive side, a different study found that people who drink two to seven glasses of wine a week are less prone to depression…  so maybe it’s not time to swear off the grapes just yet.
