FDA approves new test for colon cancer

It provides an option for some people who do not want the more invasive colonoscopy screening test.

The Food and Drug Administration has approved the first DNA-based test for colon cancer.

(NBC) - The Food and Drug Administration has approved a non-invasive, DNA-based test for colon cancer.

It provides an option for some people who do not want the more invasive colonoscopy screening test.

The new test called "Colo-Guard" is for patients with a low risk for developing the disease. It checks for DNA mutations in stool samples that can be a sign for cancerous or pre-cancerous growths.

Patients who test positive for the mutations would have to undergo a colonoscopy to confirm the results.
