That headline is misleading.A traditional Colonoscopy is still an invasive procedure because it involves inserting a flexible camera into the colon. It remains the gold standard for finding and removing polyps and taking biopsies.
What the headline is probably referring to is the development or increased use of less invasive screening options, such as:
- CT colonography (“virtual colonoscopy”), which uses CT scans to create images of the colon. If an abnormality is found, a standard colonoscopy is usually still needed to remove polyps or take tissue samples.
- Colon capsule endoscopy, where a person swallows a capsule containing a tiny camera. This may be an option for some people, but it does not replace standard colonoscopy in many situations.
- Fecal immunochemical test (FIT), a stool test used for colorectal cancer screening. A positive result is followed by a colonoscopy.
So while screening options are expanding, there is currently no new method that has made colonoscopy itself non-invasive. Standard colonoscopy is still needed when doctors need to examine the colon directly, remove polyps, or perform biopsies.
If you saw this in an article or social media post, it’s likely oversimplifying or exaggerating advances in screening technology.
