We've seen the studies that say drinking in moderation is good for your heart.  But could there be a dangerous health effect, as well?  A new study says women who drink just three alcoholic beverages a week face slightly higher chances for developing breast cancer than those that abstain.

FOX News Radio's Lilian Woo has details:

A study of more than 100,000 nurses in the U.S., many of them followed for nearly 30 years, finding women who averaged 3-6 drinks a week had a 15% higher chance of developing breast cancer than non-drinkers - also that there was no difference whether they chose liquor, beer or wine.

While the link isn't new, most previous studies found no increased risk among light drinkers.  Still the study only shows an association between alcohol and the disease.  It does not prove drinking causes breast cancer.
