EASIER COLON CANCER SCREEN?
ANCHOR LEAD: CT MAY SOON REPLACE COLONSCOPY TO SCREEN FOR COLON CANCER, ELIZABETH TRACEY REPORTS
Colonoscopy to screen for colon cancer is recommended by the American Cancer Society for everyone once they turn fifty. Now traditional colonoscopy, which involves insertion of a flexible instrument into the large intestine, may be replaced by another technique using CT. The new technique is called either virtual colonoscopy or CT colonography, says Francis Giardiello, a colon cancer expert at Johns Hopkins, and has proven comparable in the latest of a series of studies.
GIARDIELLO: What they’ve shown is that the ability of CT colongraphy to pick up polyps in the colon at least for significant polyps of the colon, seems to match the ability of a colonoscopy to do the same thing. This article supports the notion that CT colonography is a technique which will be part of our screening armamentarium. :27
