This article discusses the removal of adenomas in the colon to prevent colorectal cancer. The authors review research showing the relationship between polyp removal and carcinoma. They discuss the rate of adenoma detection with endoscopy and the overall risks of colonoscopic polypectomy. They present th...

Retrospective data suggests that colonoscopy may not be as protective of colon cancer in the proximal colon; however, prospective data on the...
Location: common in the rectum Larger than other adenomas (cauliflower-like), and often sessile Histology: finger-like projections lined by dysplastic epithelium The majority of colon carcinomas develop from adenomas (adenoma‑carcinoma sequence). However, only ∼ 5% of adenomas develop into ...
