Research suggests a link between heavy drinking and an increased risk of colorectal cancer, with some studies indicating that consuming two or more alcoholic drinks per day may raise the risk by up to 95%. The relationship between long-term alcohol use and colorectal cancer risk appears to be dose-dependent, with heavier and longer-term drinking associated with a higher risk. However, the exact magnitude of the increased risk varies across reports, with estimates ranging from 25% to 95% or more.
