Further evidence for the link between alcohol and bowel cancer is provided in a 2015 paper from the Department of Colorectal Surgery at Shanghai Jiao Tong University. This particular study focused on the consumption of beer, and found that regular beer drinkers had a 20% increased risk of bowel cancer when compared with non-drinkers or occasional drinkers (5). Furthermore, the study concluded that drinking just one more beer a day was associated with an increased likelihood of colorectal cancer (6).
