PHILADELPHIA -- Colonoscopy is the gold standard for colon cancer screening, but getting one may be challenging for some people.
In addition to the financial barriers if you don't have good insurance, patients may avoid getting screened for colon cancer because they don't want to be put under anesthesia while a doctor uses a camera at the end of a flexible tube to scan the colon and large intestine for abnormalities.
And that comes the day after the prep, during which you can have only clear liquids and must drink a less-than-pleasant liquid to clear the intestinal tract.
