X-Rays for Detecting Colon Cancer

The New England Journal of Medicine revealed a federal study of an x-ray alternative to colonoscopies. The colonography method was confirmed as effective at spotting most cancers.

The study, the largest of its kind, identified 9 out of 10 people who had cancers or large growths diagnosed previously by standard colonoscopy by using the "virtual colonoscopy" (x-ray method). Though better at ruling out cancer rather than detecting it, the virtual colonoscopy has real value in showing who needs a regular colonoscopy.

By utilizing the x-ray detection method, more people may opt to be screened as the procedure is non-invasive and involves none of the embarassment of a regular colonoscopy. Since early detection is vital in treating the various forms of colon cancers, this new screening may help many people who have shied away from the standard form of colon cancer screenings.

With costs of colonoscopies running about $3,000 per test, and x-rays costing just $300-$800, Medicare is considering paying for the cheaper, less intrusive option.

More information is available through the New England Journal of Medicine.
