The final trial examined screening with FOBT compared with standard care and inconsistently offered repeat FOBT or sigmoidoscopy with double-contrast barium enema if any samples were positive on initial testing, which resulted in decreased colorectal cancer mortality for the screened group (N=68,308; RR=0.

According to the American Cancer Society, to diagnose colorectal cancer early or even before it actually develops, all people above age 50 should undergo any one, just one, of the following procedures: 1) flexible sigmoidoscopy every 5 years; 2) colonoscopy every 10 years; 3) double-contrast barium enema every 5 years; 4) CT colonography (virtual colonoscopy) every five years.
The ACP did not endorse specific screening intervals, although many experts recommend for average-risk patients over age 50 an interval of 10 years for colonoscopy, five years for flexible sigmoidoscopy, double-contrast barium enema, and computed tomography (CT, or virtual) colonography, and annually for fecal occult blood tests.
