Alcohol linked to rising colorectal cancer deaths in younger adults
Key Points:
- Colorectal cancer has become the leading cause of cancer-related death among adults aged 50 and younger, with alcohol consumption identified as a significant, dose-dependent risk factor.
- The International Agency for Research on Cancer classifies alcoholic beverages as Group 1 carcinogens, with alcohol metabolizing into acetaldehyde, which damages DNA and disrupts the gut microbiome, increasing cancer risk.
- Drinking two or more alcoholic drinks daily raises lifetime colorectal cancer risk by at least 25%, and heavier, frequent drinking further amplifies this risk; cessation of alcohol can reduce risk over approximately 10 years.
- Other lifestyle factors that reduce colorectal cancer risk include regular exercise, avoiding smoking, maintaining a healthy weight, and consuming a high-fiber
