DNA Stool Test for Colon Cancer-Mayo Clinic

 

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 non-invasive screening test that requires no preparation or procedure. The test detects cancer or precancerous polyps by measuring DNA in your stool.
