What is the risk of death associated with colonoscopy?

The risk of death associated with colonoscopy is estimated to be approximately 0.007%, which reflects a very low incidence of mortality linked to this procedure. Colonoscopy, commonly used for screening and diagnostic purposes, is generally considered safe and effective. The low risk of death can be attributed to several factors: the screening is typically performed on healthy individuals or those with manageable conditions, and the advancement in endoscopic techniques and monitoring has significantly improved patient safety.

This estimate accounts for complications that can arise during or after the procedure, such as perforation or significant bleeding, but those occurrences are rare. As a result, colonoscopy remains a critical tool in preventing colorectal cancer through early detection and intervention, with its benefits significantly outweighing the risks involved.
