Many patients ask me about the interaction of alcohol and breast cancer.

There has been new awareness concerning the risk of alcohol consumption and breast cancer. When reviewing information about alcohol consumption, it is important to first know how a drink is defined. Twelve ounces of beer, 5 ounces of wine, and 1.5 ounces of liquor are considered a drink. The risk of breast cancer is influenced by how much you drink, how early in life you start, and how much of your life you continue.
It is a cumulative effect.


A recent Nurses Health Study published in the Journal of the American Medical Association (JAMA) looked at “cumulative average consumption” over a 28-year-period of more than 100,000 women. There was a significant increase in breast cancer cases in those women who drank as little as 3-6 drinks per week. This increased risk of 3-6 drinks per week was small but real. The greater the amount of alcohol consumed on average per week, the greater the increase in breast cancer risk.


Another important study was published recently in the journal Cancer. This study evaluated the effects of alcohol and family history on the risk of benign breast disease, a known risk factor for breast cancer. This study looked at daughters from the Nurses Health Study II. The study confirmed an increased risk of benign breast disease for girls who drank at a level of greater than 1 drink per week at age 16, greater than 2 drinks per week at age 18, and 3 drinks per week at age 19 and who had a family history of breast cancer or maternal benign breast disease. These girls had a significant increase in the incidence of benign breast disease over girls without family history of breast cancer or alcohol use. Girls without a family history did not have an increased risk with alcohol consumption.


These two studies show the influence of alcohol on breast cancer risk. The main consideration is the amount of alcohol over time. Delaying the beginning of drinking alcohol until you are older and then drinking moderately will reduce effects.

I recommend limiting yourself to 3-6 drinks per week maximum. Less if you are young and/or have a family history of breast cancer. I also recommend red wine if you like it because of the extra advantage of heart benefits.
