Two recent studies found colon screenings that require a less intensive preparation than a colonoscopy are useful in finding pre-cancerous polyps, or growths. Read the American Cancer Society news article here.
1. Researchers from the University of Pittsburgh and colleagues found that a flexible sigmoidoscopy significantly reduced colorectal cancer death rates and the rates of new cases.
Study mentioned: Schoen RE, et al. Colorectal-cancer incidence and mortality with screening flexible sigmoidoscopy. N Engl J Med. 2012 Jun 21;366(25):2345-57. PMID 22612596
2. In another study, funded by the American Cancer Society, researchers from Massachusetts General Hospital and University of California, San Francisco tested a kind of screening called computed tomographic colonography (CTC), also called “virtual colonoscopy” that doesn’t require a laxative preparation.
Study mentioned: Zalis ME. Diagnostic accuracy of laxative-free computed tomographic colonography for detection of adenomatous polyps in asymptomatic adults: a prospective evaluation. Ann Intern Med. 2012 May 15;156(10):692-702. PMID 22586008
