But what is the actual risk? I can't find any specific information. It says in https://en.wikipedia.org/wiki/Alcohol_and_cancer that in Europe 10% of cancers in males is due to alcohol, but is this mainly from heavy drinking, the two bottles of whisky a day type? It would be good to know what the risk of moderate drinking is, for example 15 units per week, it would be good if this were in an understandable number like the average years of good health lost.
