Alcohol drinking, consumption patterns and breast cancer among Danish nurses: a cohort study
The European Journal of Public Health Advance Access published online on April 18, 2007




The aim of this study was to analyse the impact of alcohol intake and drinking pattern on the risk of breast cancer.

Among alcohol consumers, weekly alcohol intake increased the risk of breast cancer with 2% for each additional drink consumed. Weekend consumption increased the risk with 4% for each additional drink consumed friday through sunday. Binge drinking of 4–5 drinks the latest weekday increased risk with 55%, compared with consumption of one drink. A possible threshold in risk estimates was found for consumption above 27 drinks per week.

For alcohol consumption above the intake most frequently reported, the risk of breast cancer is increased. The risk is minor for moderate levels but increases for each additional drink consumed during the week. Weekend consumption and binge drinking imply an additional increase in breast cancer risk.
