Lynch syndrome, or hereditary nonpolyposis colorectal cancer (HNPCC), is the most common hereditary condition predisposing for colorectal cancer. International guidelines recommend surveillance of the colorectum by colonoscopy every 1-2 years starting at the age of 20-25 years. This has been shown to reduce the incidence of, and mortality due to colorectal cancer. ...
