Cancer has been the leading cause of death in both developed and developing countries, and the rate of increase is faster than before in global population. The International Agency for Research on Cancer (IARC) estimated that ∼7.6 million cancer deaths occurred in 2008, compared with 6.2 million in 2000 [1–3]. Alcohol drinking is one of the important known lifestyle-related risk factors. Evidence from humans for carcinogenicity of alcohol is considered to be conclusive, which has been confirmed as Group 1 ‘carcinogenic to humans’ by IARC .
