The risk for both distal (left-sided) and proximal (right-sided) colorectal cancer (CRC) dropped after older patients had colonoscopy, according to results of a US study presented here at the American College of Gastroenterology (ACG) 2011 Annual Scientific Meeting and Postgraduate Course…"I think that the most surprising part is that we actually show for colonoscopy that there is risk reduction for the proximal colon," Yize Richard Wang, MD, PhD, a gastroenterology fellow at the Mayo Clinic in Jacksonville told Medscape Medical News. "Previous studies don't show that."
