DNA stool test for colon cancer — Mayo Clinic

Feb. 28, 2014

Overview

Research shows that screening for colorectal cancer saves lives. That's because screening can catch cancer early, while it's still curable. But let's face it, having a colonoscopy to look for cancer or precancerous polyps is not fun. Doctors at Mayo Clinic have studied and improved upon a noninvasive screening test that requires no preparation or procedure. The test detects cancer or precancerous polyps by measuring DNA in your stool.
