What is a colonoscopy?

This question was asked in San Francisco, California on 02/16/2012.
How is it different from other cancer procedures? I'm confused because there are so many of them for polyps and colon cancer and I don't know if each different medical procedure is for something different. Thanks.

The only test that can?examine the entire colon and remove polyps is a colonoscopy.
