Virtual GI Biopsy
Colon cancer is a deadly disease that, thanks to screening tools, can be prevented and cured if caught early. One of the current ways to look for cancer or pre-cancerous polyps is with colonoscopy. That's the test during which doctors use a scope to spot and remove polyps which they send to a lab for diagnosis. But now, a new technology allows doctors to determine if you have pre-cancerous polyps without having to remove them first. Doctors at Mayo Clinic say it could save many people from having unnecessary biopsies.
