Flat adenomas measuring 6 mm or greater are, however, uncommon in a typical Western screening population, and advanced neoplasms are rare. Flat lesions should therefore not be considered a significant drawback for virtual colonoscopy screening (Pickhardt et al. 2004b). 

Secondary prevention is aimed at preventing malignancy in a population that has already manifested an initial disease process. Secondary prevention includes procedures ranging from colonoscopic removal of precan-cerous polyps detected during screening colonoscopy to total colectomy for high-risk individuals (e.g., familial adenomatous polyposis).

For these and other reasons (i.e., obviously hydrocolonic sonography does not offer the possibility/ opportunity to collect biopsies or remove polyps), although less invasive and expensive than colonoscopy, the use of hydrocolonic sonography, as a screening tool for colorectal cancer, should be evaluated with due care.
