Lesions in the colon associated with an increased risk of cancer

Lesions flattened, apparently common in the colon and difficult to detect, allegedly linked to a greater risk of cancer of the large intestine that some polyps, according to a study published Wednesday in the Journal of the AmericCancer (99%) Preventive medicine (99%) Medical personnel (75%) Journal of the American Medical Association (74%) an Medical Association

Efforts to prevent colon cancer, the second leading cause of death from cancer in the United States, focusing on the detection and removal of polyps during colonoscopy. But an analysis of data from 1819 patients in California revealed that there are nearly ten times more likely that these lesions plates contain cancer cells that polyps whatever their size. These lesions, when they form a depression on the membrane of the intestinal wall, even more difficult to detect during an examination, present the greatest risk (33%) to evolve into cancer. "Future studies of these lesions should better evaluate whether their diagnosis and ablation have an effect on the prevention and mortality from colorectal cancer," writes Dr. Roy Soetikno, the main sponsor of this research. In an editorial accompanying the study, Dr. David Lieberman, of the faculty of medicine in Oregon (Washington), notes that "these lesions or neoplasms probably appear to be more likely to contain cancer cells." And to the extent that they are difficult to detect, "it is very important that colonoscopies are made with the greatest attention," he says noting "we do not know with certainty that it is the most common method Efficient lead. " Studies have shown that 0.3 to 0.9% of those who had a colonoscopy and the removal of one or more polyps develop colon cancer a few years later. Some doctors believe that a large proportion of these cases could be explained by the non-detection of these lesions plates or by the fact that they have not been entirely removed.
