DNA Stool Testing May Screen For Multiple Cancers

Performing DNA testing of a person's stool may accurately screen for a variety of cancers found in the pancreas, stomach, bile ducts and esophagus, reports U.S. News & World Report.

Doctors have approached cancer diagnosis one organ at time; however with testing DNA from stool samples, doctors could screen multiple organs to possibly detect cancers earlier, say Mayo Clinic researchers who conducted a recent study on the procedure.

The test works by checking patient stool for the DNA of cells regularly shed from the surface of several types of tumors.

Findings from the study report the test found 65% of esophageal cancers, 62% of pancreatic cancers, 75% of bile duct and gallbladder cancers and 100% of stomach and colorectal cancers.  The test found both early-stage and late-stage cancers successfully.
