---------------- While the majority of colon cancers were thought to develop from polyps, a new study challenges that assumption and points out that so-called non-polypoid (flat or depressed) lesions in the colon are also likely to turn into cancer. A study in the March 5 issue of the Journal of the American Medical Association reports that such lesions were present in almost 10 percent of people screened for the study, and that these lesions were 10 times more likely to be cancerous than polyps were. ... Generally, non-polypoid lesions can be removed at the time of a colonoscopy. If the center where you have your colonscopy done doesn't have the expertise yet, you may have to undergo a second procedure to have the lesion removed.
