Thus several strategies exist to carry out an active prevention of colorrectal cancer:
Individuals at average risk need to be tested by the age of 50, and the most effective test is to perform a colonoscopy every 10 years (if no polyp have been found). As an alternative, fecal occult blood test (FOBT) can be offered anually of each two years. Although it is not routinely carried out in our country, sigmoidoscopy each 3-5 years can also be an alternative.
It is mandatory to alert people at high risk for colorrectal cáncer to be tested by colonoscopy at closer intervals, including people with personal history of prior colorrectal cáncer or polyps, relatives with colorrectal cáncer, familial polyposis síndromes and chronic colonic diseases such inflammatory bowel diseases.
