Alcohol has been proven to have serious side effects that can be detrimental to one’s health, as science becomes more advanced researchers are finding out what else alcohol consumption may lead to. New research has shown that women who have three to six alcoholic drinks a week are at slightly increased risk of developing breast cancer compared with women who don’t drink at all.
More than 100,000 nurses were observed for almost 30 years, according to USA Today. Most previous studies on alcohol and breast cancer have found no increased risk for the disease among women who are light drinkers, according to the article.
Women who had three to six drinks a week had a 15 percent increased risk of developing breast cancer compared with nondrinkers, equating to about four additional cases of breast cancer per 1,000 women. A woman’s risk of the disease increased the more she drank, regardless of whether she drank:
In a news release, the study authors said that while the exact way in which alcohol may lead to breast cancer is not known, one probable explanation may involve alcohol’s effect on circulating estrogen levels. Either way, women should be aware of the potential for cancer due to heavy drinking, everybody is different and there is no telling how it may affect you.
The study appears in the Journal of the American Medical Association.
