A colonoscopy looks for polyps or cancer whether or not you have any specific risk factors—even if you have no symptoms. This test allows us to catch colon polyps and remove them to try to prevent cancer altogether, and to catch colorectal cancer in its earliest stages, when it is easiest to treat.
Preparing for Your Colonoscopy (Colonoscopy Prep)
Before your colonoscopy, you need to clean out your colon (colon prep). Colon prep usually takes two days.
Colon prep can be time consuming and a little uncomfortable, but it is absolutely necessary for a quick and successful colonoscopy.
To make your prep successful, you should consume a liquid diet (such as clear broth, black coffee, tea, apple juice, clear soft drinks, and popsicles) the entire day before your colonoscopy.
