Introduction: Nearly two thirds of colorectal cancers occur in the rectum or sigmoid colon. It is the third most common cancer in resource-rich countries, accounting for about 20,000 deaths each year in the UK, and 60,000 each year in the USA.
Methods And Outcomes: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of screening for colorectal cancer? We searched: Medline, Embase, The Cochrane Library and other important databases up to November 2006 (BMJ Clinical evidence reviews are updated periodically, please check our website for the most up-to-date version of this review).
