The incidence of rectal cancer in the European Union is $125 000 per year, ie $35% of the total colorectal cancer incidence, reflecting 15–25 cases/100000 population per year and is predicted to increase further in both genders. The mortality is 4–10/100000 population per year. Median age at diagnosis is $70 years, but predictions suggest that this figure will rise in the future.

Evidence is accumulating that rectal cancer is distinct from colon cancer with different aetiologies and risk factors [1–2], possibly reflecting different environmental exposures. High body mass index, body or abdominal fatness and diabetes type II are seen as risk factors. Longstanding ulcerative colitis and Crohn’s disease affecting the rectum, excessive consumption of red or processed meat and tobacco as well as moderate/heavy alcohol use increase the risk.
