A large number of epidemiological studies assessing the link between alcohol consumption and risk of cancer have found strong associations for increased risk in a number of cancers, namely those of the Upper Aero Digestive Tract (oral cavity, larynx, pharynx and oesophagus (UADT)), stomach, colon and breast. The evidence is inconsistent and varies in the degree of significance for the different types of cancer (Bagnardi, 2001, Seitz et al, 2004, Poschl, 2004). For the purposes of this review, I have chosen to discuss alcohol in terms of units where 9 grams of ethanol equates 1 unit (?).

Alcohol consumption has been linked to a wide variety of cancers, the main ones being of the Upper Digestive Tract (UDT), stomach and colon. It has been suggested that this is due to these particular organs being subjected to the highest concentrations of alcohol and the ethanol may be to blame for carcinogenic effects leading to cancers.

Gronbaek's study into alcohol consumption and oesophageal cancer ........... Gronbaek went on to suggest that the type of alcoholic beverage consumed may have an effect. Wine has long been stated as having positive benefits for the heart and in a few recent studies has been found to be less of a risk factor in the development of cancer. So and so suggests this is due to the compound resveratol present in wine that may be found to be anti carcinogenic. The compound can not be found in beer and spirits where the negative compound thought to be carcinogenic is nitrosamines.

Although the intake of alcohol is extremely high, Castellsague et al 2004 found a similar relationship in Spain. The study carried out in Spain suggested that non-smoking, moderate drinkers (units?) had a significant increase in developing oral cancer, and that consuming spirits may contribute to 77%...
