Improved Stool Screening Test Finds DNA Changes

Too many people avoid colonoscopy.  Too invasive, they say.  Too scary, too risky. There may be an answer for them in an improved stool test that looks for DNA that is changed in both colorectal cancer and some precancerous polyps. Of course, if the stool test identifies possible polyps or cancer, a colonoscopy is critical to evaluate the findings and remove polyps. The test that looks for methylated DNA in human feces, found 85 percent of cancers and 64 percent of large adenomas.  There were few false positives.  Only one in ten follow-up colonoscopies didn’t confirm cancer or adenomas.
