The report is published in the latest issue of the Annals of Internal Medicine.
The Task Force identified two screening methods that have been shown to reduce death from colorectal cancer: the fecal occult blood test and flexible sigmoidoscopy.
They also recommended colonoscopy but say the evidence that it reduces death from colorectal cancer is indirect.
The Task Force did not recommend a specific screening test, saying instead that patients and their physicians should discuss the advantages and disadvantages of the tests and decide which test is best for them.

The frequency of screening depends on the test.
Adults with known risk factors for colorectal cancer, such as a family or personal history of colorectal cancer, need more intensive screening.
