Awareness of the influence of lifestyle on cancer risks has stimulated research into the relationship between drinking and cancers. Alcohol consumption increases the risk of cancers of all parts of the digestive tract except the stomach. The link becomes progressively weaker from mouth to rectum. The risk is tripled for cancer of the mouth and throat, and doubled for cancer of the oesophagus. The mucosal surfaces of these organs come into direct contact with imbibed alcohol, and it has been suggested that the risk of developing these cancers is less if the alcohol is consumed with food.
