The American Cancer Society says an uptick in colon cancer cases in the 45-49 age group is a result of lowered screening ages leading to earlier detection.

Limiting alcohol consumption is also important as its metabolization produces a toxic substance that can damage DNA and potentially lead to uncontrolled cell growth .
