Which statement about colonoscopy is true regarding risks?

Explanation:
Colonoscopy carries real, procedure-related risks, with perforation of the colon wall and bleeding being the most important and direct complications. Perforation can occur from instrument passage or during therapeutic steps like polype removal, while bleeding is more likely after biopsies or polypectomies and may require additional intervention. These risks exist even though the test is generally safe and most patients have no complications. Sedation and bowel preparation can also carry their own risks, but the statement that best reflects risks specific to the procedure itself is the possibility of perforation and bleeding.
