Screening Modalities

From the 2008 guideline from the American Cancer Society, the US Multi-Society Task Force on Colorectal Cancer, and the American College of Radiology:

Testing Options for the Early Detection of Colorectal Cancer and Adenomatous Polyps for Asymptomatic Adults Aged 50 Years and Older
	Tests that Detect Adenomatous Polyps and Cancer
	Flexible sigmoidoscopy every 5 years, or Colonoscopy every 10 years, or Double-contrast barium enema every 5 years, or Computer tomographic colonography every 5 years
	Tests that Primarily Detect Cancer
	Annual guiac-based fecal occult blood test with high test sensitivity for cancer, or Annual fecal immunochemical test with high test sensitivity for cancer, or Stool DNA test with high sensitivity for cancer, interval uncertain
