What Happens If a Polyp Is Found During Your Colonoscopy

If you have been told a polyp was found during your colonoscopy, it is natural to feel concerned. But finding and removing polyps is not a sign that something went wrong — it is the colonoscopy doing exactly what it is designed to do.

What is a colon polyp?

A polyp is a small growth on the inner lining of the colon or rectum. Polyps are extremely common, especially as we get older, and the large majority are benign. Most cause no symptoms at all, which is why they are typically discovered during screening rather than because of any problem.

Why polyps are removed

The reason polyps matter is that certain types can, over a period of years, slowly develop into colorectal cancer. Removing a polyp interrupts that process before it can happen. This is the essential insight behind colonoscopy as a screening tool: it does not just detect cancer, it prevents it by removing the growths that could become cancer.

Not all polyps are the same

Polyps fall into a few broad categories, and the type matters:

• Adenomatous polyps (adenomas) are the most common type with the potential to become cancerous over time. Most colorectal cancers begin as adenomas. Removing them is genuinely preventive.
• Hyperplastic polyps are generally small and carry a very low risk of becoming cancerous.
• Sessile serrated polyps are a type that also carries some cancer potential and is typically removed and monitored.

After removal, polyps are sent to a pathologist, who examines the tissue and determines the type. This is what guides your physician's recommendation for when you should return.

How polyps are removed

In most cases, polyps are removed painlessly during the same colonoscopy in which they are found — you will not feel it, and it does not extend recovery. Removing polyps during the procedure is routine and is part of what a colonoscopy is designed to do.

What happens after

Once the pathology results are back, usually within one to two weeks, your physician will discuss what was found and recommend a follow-up interval. If an adenoma or serrated polyp was removed, you may be advised to return in three to five years rather than the standard ten, depending on the number, size, and type of polyps found. This shorter interval is simply a way of keeping a closer eye on things — not a cause for worry.

The reassuring takeaway

A polyp found is a problem solved. The growth that might have caused trouble years down the line has been removed, examined, and accounted for. Far from being bad news, it is often the clearest example of preventive medicine working exactly as intended.
