“Colonoscop-ease” — The Discovery Files

Everyone cringes at the dreaded colonoscopy… so much so, that only a very small percentage of people who should get this procedure, actually do. Researchers at Northwestern University are working on a novel alternative that uses optical technology to screen the base of the colon for precancerous changes. The thought is that one day, this much less invasive procedure could be done by primary care physicians and could replace the traditional colonscopy for many people.
