Habitual consumers of alcohol are highly liable to have advanced and multiple adenomas in their colon and rectum.

This study was carried out to determine the role alcohol consumption play in the development and progression of colorectal adenomas—the precursor lesion of colorectal cancer. Researchers looked at the alcohol drinking habits of 212 patients with colorectal adenomas. 

Researchers found high rates of advanced and multiple adenomas in the colon and rectum of individuals in the alcohol drinking group compared to their non-drinking counterparts. This study provides evidence that regular drinking of alcohol may speed up the development, growth, and multiplication of colorectal adenomas.
