Does the pattern of drinking affect the risk of breast cancer?
There are no studies that compare the effects of drinking every day to the effects of drinking only occasionally. In other words, it is not known whether drinking one drink every day, such as drinking wine with a meal, has the same relationship to breast cancer risk as binge drinking, such as having 7 drinks on a Saturday night. What kinds of alcoholic beverages have been associated with breast cancer risk? Some researchers reported that the consumption of beer and hard liquor, such as vodka and gin, had a greater association with breast cancer risk than the consumption of wine. Others have reported no difference in the type of alcoholic beverage consumed. Studies in European countries, such as Italy, where wine is consumed regularly at dinner, have also reported that the consumption of alcohol is associated with increased breast cancer risk. Therefore, the current evidence suggests that it is probably the alcohol in wine, beer and liquor and not some other component of these beverages
