According to the American Cancer Society, the use of alcohol is linked to an increased risk of developing breast cancer. The risk increases with the amount of alcohol consumed. Compared with non-drinkers, women who consume 1 alcoholic drink a day have a very small increase in risk. Those who have 2 to 5 drinks daily have about 1½ times the risk of women who don’t drink alcohol.
However Medscape reports that several other studies on the effects of alcohol in regard to breast cancer have been inconclusive. A new study suggests that alcohol may not have any effect on whether you survive the disease. In fact, researchers found that being a moderate drinker may actually improve your chances of overall survival.
Excessive alcohol use is also known to increase the risk of developing several other types of cancer.
