Various Classes of Colonic Polyps: An Overview

Various classes of colon polyps: a comprehensive guide.

Colon polyps are growths that project from the inner lining of the colon or rectum, and while most are noncancerous, some can develop into malignant tumours. Here's a breakdown of the common types of colon polyps, their risks, and why regular screenings are crucial.

Adenomatous Polyps (Adenomas)

Adenomas are the most common type of colon polyps, accounting for about 70% of adenomatous polyps. They can be classified by their growth patterns:

Tubular adenomas: Smaller, tube-shaped growths.
Villous adenomas: Larger, cauliflower-like (shaggy) growths.
Tubulovillous adenomas: Mixed features of both tubular and villous.

Advanced adenomas (larger than 1 cm or with villous/tubulovillous features) have a higher risk of becoming cancerous. Finding and removing these early reduces cancer risk. If someone has had adenomas, they have an increased likelihood of developing more and need more frequent screenings. Family members may also have increased risk and should consider earlier screening.

Sessile Serrated Polyps (Sessile Serrated Adenomas)

Sessile serrated polyps, also called sessile serrated adenomas, carry a significant risk of progression to colorectal cancer, especially if they are large or have dysplasia.

Hyperplastic Polyps

Generally considered benign with very low risk of becoming cancerous, hyperplastic polyps are often small and located in the distal colon or rectum. Exceptions include hyperplastic polyps in the right colon or those associated with certain hereditary syndromes, which may have some risk.

Inflammatory Polyps

Usually benign and not considered precancerous, inflammatory polyps occur most often in people with inflammatory bowel disease.

Hamartomatous Polyps

Hamartomatous polyps typically do not have malignant potential, except in rare familial syndromes where the risk is higher. Hamartomatous polyps are generally noncancerous and are more common in children.

In summary, adenomatous polyps and serrated polyps are the main precursors with substantial cancer risk, whereas hyperplastic, inflammatory, and hamartomatous polyps are unlikely to become cancerous. The risk of cancer increases with polyp size, histologic features, and number of adenomas found.

Colorectal cancer most commonly arises from these adenomatous polyps and their progression to adenocarcinoma, which is the predominant type of colorectal cancer. After a person has polyps removed, a doctor may monitor them more closely and test them more frequently due to an increased risk of developing cancerous polyps.

In the U.S., approximately 60% of adults have colon polyps. During a colon polypectomy, a surgeon inserts a long, thin, flexible tube with a camera and light on the end through the rectum to locate and remove polyps. Surgeons can use different techniques to remove polyps, including cold forceps polypectomy, hot forceps polypectomy, and snare polypectomy.

It's essential for people to speak with a healthcare professional if they experience symptoms like unexplained changes in bowel habits, blood in stool, nausea, vomiting, fever, unexplained exhaustion, and bruising easily, or if symptoms occur following the removal of polyps. Complex polyps are polyps that are difficult or unsafe to remove using regular techniques.

Regular screenings can help detect polyps early and reduce the risk of colorectal cancer. If you're over 50, or have a family history of colorectal cancer, consider speaking with your healthcare provider about scheduling a colonoscopy.
