CANCER DIGEST – Aug. 12, 2014 –The U.S. FDA today approved Cologuard, the first stool-based DNA colorectal screening test that detects genetic mutations that may indicate colon cancer or precursors to cancer.

Using a stool sample, Cologuard detects blood components and certain mutations associated with colorectal cancer in the DNA of cells shed by advanced adenomas as stool moves through the large intestine and rectum. Patients with positive test results are advised to undergo a diagnostic colonoscopy.
