"Adenomatous colon polyps are thought to progress histologically from adenoma to dysplasia, to carcinoma; thus screening detection of precancerous polyps is considered useful. The individual risk for a polyp progressing to cancer is low, in the order of 3% and it is thought that it takes 10-15 years for a polyp to devolve into carcinoma."

"There are multiple polyposis syndromes which increase the risk of colon polyps."
"Because of the benefits of screening, screening studies (usually immunochemical faecal occult blood testing and/or colonoscopy) are recommended at age 50 for men and women, but the actual screening program depends on the patient's region and risk factors. Screening at age 40 years or younger is recommended for patients at higher risk (e.g. familial adenomatous polyposis)."
