Alcohol consumption is a risk factor for a number of cancers. However, the proportions of these cancers that are attributable to alcohol consumption are less clear. In this study, investigators determined the burden of cancer attributable to current and former alcohol consumption among 110,000 men and 255,000 women (age range, 35–70) in eight western European countries who were cancer-free at recruitment between 1992 and 2000. Follow-up ended between 2002 and 2005.
Overall, 10% of total cancers in men and 3% of total cancers in women were attributable to alcohol consumption. These percentages were higher for specific cancers. The alcohol-attributable fractions in men and women were, respectively, 44% and 25% for upper aerodigestive tract can…
