Alcohol drinking and colorectal cancer risk: an overall and dose-response analysis of published studies.

Colorectal cancer is more likely to occur in individuals who are heavy or moderate drinkers of alcohol.

The aim of this research work was to evaluate the relationship between alcohol consumption and the risk of colorectal adenoma by meta-analysis. Data extracted from 61 studies were analyzed in this meta-analysis.

Researchers observed a greater colorectal cancer risk was associated with heavy (4 or more drinks per day) and moderate (2-3 drinks per day) intake of alcohol. On the other hand, the consumption of less than a drink per day was found to have little or no effect on colorectal cancer risk. The findings of this meta-analysis show that generous intake of alcohol may increase an individual’s chances of developing colorectal cancer.
