You have a few informational
options, depending upon your current level of understanding about colon
polyps, colon cancer, and types of screening tests available.
The
slide show is a very basic and easy to understand educational overview on colon cancer
screening---background, trends, testing options (including a comparison of
colonoscopy and virtual colonoscopy). Although a few minor advancements and
procedural adjustments have been made since we created these images,
conceptually, the information remains quite relevant.
A slightly more technical article with excellent images can be found at the
Johns Hopkins University website.
Additionally, you may view a well done Fox News report with an
animated
colonoscopy.
