E.

Two thirds of polyps found on colonoscopy are adenomas, which are by definition dysplastic and, therefore, have malignant potential. They are classified based on glandular architecture (tubular, villous, tubulovillous) and degree of dysplasia (low- or high-grade). Joint guidelines from the American College of Gastroenterology and the American Gastroenterological Association recommend surveillance colonoscopy in 5 years for patients with 1 or 2 small (<1 cm) tubular adenomas and no family history of colon cancer. Patients with multiple adenomas (>3), a large adenoma (>1 cm), villous histology or high-grade dysplasia, or a positive family history of colon cancer should undergo repeat surveillance colonoscopy in 3 years
