Episode notes
Rising Colon Cancer in Young Adults
- Colon cancer rates are rising rapidly among adults under 50, now the leading cause of cancer death in men under 50 in the US.
- By 2030, colon cancer may become the top cause of cancer death for both men and women under 50, showing a major epidemiological shift.
Start Screening Early
- Start colon cancer screening at age 45 for average risk individuals and earlier if family history exists.
- Screening can be invasive like colonoscopy or non-invasive stool tests, both effective for early detection and prevention.
Dietary Changes for Prevention
- Reduce intake of red and processed meats and lower alcohol consumption to decrease colon cancer risk.
- Even moderate alcohol may increase risk; less intake is better for reducing colon cancer chances.
