New Colon Cancer Test Shows Promise

continued...

Roswell Park Cancer Center medical director Judy L. Smith, MD, tells WebMD that we may still be a decade away from a simple blood or fecal test that is as effective as colonoscopy for detecting cancer and precancerous polyps.

"It is not yet clear exactly what the best utilization of this test will be," she says. "It may turn out to be an ancillary test to be used along with colonoscopy. This, in addition to other tools being developed, such as virtual colonoscopy, will probably not replace other screening methods. But they will give us other tools in our armamentarium to find cancer early and cure the patient."
