If you’re referring to a claim that colonoscopy is being replaced by a non-invasive method, there is some important context.
Traditional colonoscopy is still an established examination in which a flexible camera is inserted through the rectum to inspect the colon. It can also allow doctors to remove polyps or take tissue samples during the same procedure.
There are already less-invasive alternatives for colorectal-cancer screening, including:
-
Stool-based tests, such as FIT, which look for hidden blood.
-
Stool DNA tests, which look for blood and certain DNA changes associated with colorectal cancer.
-
CT colonography (virtual colonoscopy), which uses CT imaging rather than a camera inserted through the entire colon.
However, these alternatives don’t make conventional colonoscopy obsolete. If a screening test finds something abnormal, a conventional colonoscopy may still be needed for confirmation, biopsy, or polyp removal.
If you share part 2 of the claim, I can explain exactly what the “new method” refers to and whether the statement is accurate.
