BMJ reports that new guidelines from all four UK chief medical officers warn that drinking any level of alcohol raises the risk of a range of cancers. An expert advisory group examined the evidence from 44 systematic reviews and meta-analyses published since a 1995 report and concluded that there was strong evidence that the risk of a range of cancers, particularly breast cancer, increased directly in line with consumption of any amount of alcohol. Another recent report from the UK Committee on Carcinogenicity said that between 4% and 6% of all new cancers in the UK in 2013 were caused by alcohol consumption.
