“No studies have shown that the potential existence of a protective effect for cardiovascular diseases or type 2 diabetes also reduces the risk of cancer for an individual consumer. Evidence does not indicate the existence of a particular threshold at which the carcinogenic effects of alcohol start to manifest in the human body. As such, no safe amount of alcohol consumption for cancers and health can be established. Alcohol consumers should be objectively informed about the risks of cancer and other health conditions associated with alcohol consumption.”
