Stool DNA and Colorectal-Cancer Screening

Colorectal-cancer screening in the United States is a success story. The American Cancer Society recently reported that rates of death from colorectal cancer are down by 46% from their peak.1 There is good evidence that screening efforts have played an important role in the trend.2 However, work remains to be done, since approximately one third of Americans report not being current with screening.3 One approach to increase screening uptake is to broaden the available test options. On the basis of current U.S. Preventive Services Task Force guidelines, there are three recommended options: fecal occult blood testing, flexible sigmoidoscopy, and colonoscopy. . . .
