However, he said, “You cause more harm than good when you’re screening too frequently.

How accurate are colonoscopies?

Is overuse of screening colonoscopies a problem?

Douglas Rex, M.D., a professor at the Indiana University School of Medicine and past president of the American College of Gastroenterology, says overuse of screening colonoscopies may not be as common as Sheffield’s research suggests.
