abstract: Development of colon cancer is now believed to result from a series of inherited or acquired mutations in DNA. Convincing evidence that colonoscopic polypectomy prevents colorectal cancer is now available. A consensus panel recommended that all patients with duodenal and gastric ulcers who are infected with H pylori on first presentation be treated with antimicrobial agents.
