Overview. A colon polyp is a small clump of cells that forms on the lining of the colon. Most colon polyps are harmless. But over time, some colon polyps can develop into colon cancer, which is often fatal when found in its later stages.
Polyp size measurements are highly sensitive to such threshold changes. Park et al found that polyp size measurements in the pig colon model were most accurately measured when the surface rendering threshold was set at approximately −500 HU, midway between air and water CT attenuation. The mean measurement difference between the observed and ...
What Is the Average Size of a Colon Polyp? Colon polyps range in diameter from less than a quarter of an inch to several inches, according to the American Society for Gastrointestinal Endoscopy. Polyps can be flat or mushroom-shaped and can occur in several places in the gastrointestinal tract.

Adenomatous polyps, or adenomas, are polyps that grow on the lining of the colon and which carry a high risk of cancer.The adenomatous polyp is considered pre-malignant, i.e., likely to develop into colon cancer. The other types of polyps that can occur in the colon are hyperplastic and inflammatory polyps, which are unlikely to develop into colorectal cancer.
Colon polyps are treated by endoscopic removal and occasionally by surgery. Follow-up surveillance of patients with colon polyps depends on the presence of a family history of cancer, the number of polyps that are found, the size of the polyps, and the polyps' histology, and can vary between three and 10 years.
Virtually all colon cancer develops from polyps in the colon. Polyps don't always become cancerous, but your risk of developing cancer increases with the number and size of colon polyps you have. A personal or family history of polyps puts you at higher risk for colon cancer as well.
Polyps are small benign tumors in the internal lining of the colon or rectum. They are quite common in people over 50 years old, and that doesn’t mean they would eventually get colon cancer. So, if you’ve been diagnosed with polyps and read they can become cancer, you should know that is true, but it is not what usually happens.
Colon polyps can vary in size and shape and are frequently harmless. However, the vast majority of colon cancers start out as benign polyps. People age 50 and older are at an increased risk of colon polyps. Colonoscopy is regarded as the best means for detecting colon polyps. Once identified, they can be safely removed.
