Recommendations for colon cancer screening

    
Current recommendations for colon cancer screening vary according to risk category.  

For average risk individuals, screening should start at age 50 as outlined below:

Preferred screening method

• Colonoscopy every 10 years  

Alternatives

• Fecal Occult Blood Test (FBOT) yearly
• Flexible Sigmoidoscopy every 5 years
• Double Contrast Barium Enema (DCBE) every 5 years

Patients are at a higher than average risk if any of the following apply:

• A first degree relative was diagnosed with colon cancer
• A first degree relative had adenomatous (pre-cancerous) polyps
• Patient has inflammatory bowel disease

In these situations, colon cancer screening should start at 40 years old.

Screening recommendations may change according to personal history, findings during a colonoscopy, and the doctor's discretion.
