RT Journal Article SR Electronic T1 Colorectal cancer screening lacks evidence of benefit JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 545 OP 554 VO 74 IS 8 A1 Moayyedi, Paul YR 2007 UL http://www.ccjm.org/content/74/8/545.abstract AB Although some studies indicate that screening with fecal occult blood testing or colonoscopy prevents deaths from colorectal cancer, the benefits may be offset by more deaths from other causes. Whether this phenomenon is due to anxiety, test bias, or merely chance, more evidence is needed; widespread screening in the general population is premature.
