Virtual colonoscopy represents an important advance in colorectal cancer screening.
It is less invasive than a traditional colonoscopy, usually does not require sedation, and is relatively quick to perform.
However, it is not a complete replacement for standard colonoscopy.

If abnormalities are found, a traditional colonoscopy is often still needed to remove polyps or obtain tissue samples.
If you are approaching the recommended screening age or have risk factors for colorectal cancer, talk with your healthcare provider about which screening option is most appropriate for you.
The best screening test is the one that gets done.
