WORLDWIDE – Heavy, long-term alcohol use is being linked to a sharply higher risk of colorectal cancer, according to a new study published in the journal Cancer. Researchers found people with consistent heavy drinking habits faced up to a 91% higher risk, with the strongest link seen in rectal cancer. Experts told ABC News that quitting or reducing alcohol may lower pre-cancer risk, calling alcohol a well-established carcinogen. The findings come as colorectal cancer rates rise, especially among younger adults, with doctors urging early screening and lifestyle changes.
