Endoscopy Prevents Colon Cancer Deaths
Arch Fam Med. 1999;8:34.
Proctosigmoidoscopy, colonoscopy, and polypectomy are associated with lower mortality from colorectal cancer (odds ratio, 0.41; 95% CI, 0.33-0.50), with the protective effect lasting about 5 years. (Arch Intern Med. 1995;155:1741-1748.)
