FDA approves more reliable at-home screening test for colon cancer

The US Food and Drug Administration last week approved a new at-home stool test to screen for colon cancer that’s better at detecting cancer than currently-used tests that check for hidden blood in the stool. Called Cologuard, it’s the first non-invasive test to detect the presence of DNA mutations, as well as blood, that could indicate cancerous growths or precancerous polyps.

In a head to head trial involving more than 10,000 patients, Cologuard accurately detected cancers and advanced adenomas more often than fecal immunochemical testing (FIT), which had been the most reliable stool test on the market.
