What Happens If Polyps Are Found During Colonoscopy?

Being told “we found polyps” can sound alarming, especially if you were expecting a simple all-clear. In reality, finding and removing polyps is one of the main reasons colonoscopy is so valuable. A polyp is a growth from the lining of the bowel. Many polyps are benign, but some are considered pre-cancerous, which means removing them can reduce future bowel cancer risk.

This article explains what happens during the procedure, why polyps are sent for pathology, what the different result categories usually mean, and how follow-up intervals are decided. It is written for patients who have had a colonoscopy, are about to have one, or have received a positive stool test and want to understand what might happen next.

What is a bowel polyp?

A bowel polyp is a small growth on the inner lining of the colon or rectum. Some are flat, some are slightly raised, and some sit on a stalk. Polyps can vary from tiny bumps to larger lesions that require more careful removal. The appearance at colonoscopy gives clues, but pathology is needed to confirm the type.

The important point is that “polyp” is a description, not a final diagnosis. Hyperplastic polyps, adenomas and serrated lesions have different implications. Some polyps carry little concern, while others influence future surveillance. That is why your colonoscopy report and pathology result are interpreted together.

Why removing polyps matters

Bowel cancer often develops over time from changes in the bowel lining, including some types of polyps. Colonoscopy allows the doctor to inspect the colon and remove many polyps before they cause symptoms. Bowel Cancer Australia and other patient resources explain that polyp detection and removal is a key preventive advantage of colonoscopy.

Patients sometimes ask why they need a colonoscopy if they feel completely well. The answer is that polyps often do not cause pain, bleeding or bowel changes. A person can have pre-cancerous polyps and no symptoms. That is why stool tests and colonoscopy are used to find early changes before a cancer declares itself.

How polyps are removed during colonoscopy

Small polyps may be removed with tiny forceps or a cold snare. Larger polyps may need a snare technique, injection beneath the polyp, cautery or advanced resection methods. Removal is performed through the colonoscope, so there is usually no external incision. The tissue is retrieved where possible and sent to pathology.

Not every polyp can or should be removed in one routine procedure. Very large, complex or awkwardly positioned polyps may need referral for advanced endoscopic removal or, less commonly, surgery. If that happens, the priority is safe, complete treatment rather than rushing. Your doctor will explain what was done and what still needs to happen.

What the pathology result tells you

The pathology report usually comments on the type of polyp, whether there is dysplasia, whether any cancer is present, and sometimes whether the polyp appears completely removed. Adenomas and sessile serrated lesions are often considered pre-cancerous categories. That does not mean cancer was found; it means the polyp had features that justify removal and future surveillance.

This is also why the follow-up plan may not be final on the day of the procedure. The endoscopist may provide an initial impression, but the official recall recommendation often waits for histology. A “small polyp removed” and a “large advanced adenoma removed” can lead to different surveillance advice.

What if the polyp is cancerous?

If cancer is found in a polyp, the next steps depend on how early it is, whether it appears completely removed, how deep it extends, and whether there are high-risk features. Some very early cancers removed within a polyp may be managed with close follow-up, while others need surgery or multidisciplinary cancer care. The pathology result guides this decision.

A cancerous polyp is not something to interpret from a single line in a report without medical explanation. The best next step is a dedicated appointment to review the colonoscopy images, pathology, staging requirements if any, and treatment pathway. Patients should be given time to ask questions and understand what is known and what still needs to be clarified.

How follow-up colonoscopy timing is decided

Follow-up is based on risk. Important factors include how many polyps were found, their size, whether they were adenomas or serrated lesions, whether dysplasia was present, how good the bowel preparation was, whether removal was complete, and your personal or family history. This is why two patients can have “polyps” and receive different recall intervals.

At Colonoscopy Brisbane, the aim is to give the patient and GP a clear results letter with the findings, pathology summary and recommended recall. If the colonoscopy was arranged through direct-access endoscopy, this communication is especially important because the GP remains central to long-term preventive care.

What patients should ask after polyps are found

Good questions include: How many polyps were removed? Were they completely removed? What type were they? Were any advanced features present? When should I have the next colonoscopy? Should my family members do anything differently? Was the bowel preparation good enough to see clearly? Do I need to change medications or avoid anything after removal?

Most patients do not need to memorise every technical detail. What matters is that you understand the overall risk category and the next action. If the recommendation is a repeat colonoscopy, put the recall into your calendar and make sure your GP has the report. Lost follow-up is one of the easiest preventable problems in bowel cancer prevention.

How to reduce future bowel cancer risk

Polyp removal is one part of prevention. Other practical steps include participating in the National Bowel Cancer Screening Program if eligible, maintaining a healthy weight, staying physically active, avoiding smoking, moderating alcohol, and discussing family history with your GP. Symptoms such as rectal bleeding, iron deficiency or unexplained bowel habit change should be assessed even if you are not yet due for screening.

If you have had polyps before, future surveillance should be individualised. Patients with previous polyps, positive stool tests, rectal bleeding or family history concerns can review colonoscopy options in Brisbane and speak with their GP about referral.

When to seek urgent medical attention

Do not wait for an outpatient appointment if you have severe or rapidly worsening pain, persistent vomiting, fainting, a hard tender lump that will not reduce, fever, jaundice, black stools, large-volume bleeding, chest pain, shortness of breath, or symptoms that feel unsafe to you. In those situations, attend the closest emergency department or call emergency services.

Brisbane patient pathway

For non-urgent symptoms, the usual pathway is to see your GP first, arrange appropriate blood tests or imaging if needed, then obtain a referral for specialist assessment. At Colonoscopy Brisbane, Dr Goutham Sivasuthan reviews the history, examines the relevant area where appropriate, explains likely causes in plain language, and outlines the options. Patients can make an appointment online or call the rooms if they already have a referral.

If you have a positive stool test, previous polyps or symptoms such as rectal bleeding, ask your GP whether colonoscopy is appropriate. The goal is not just diagnosis; it is prevention.

How to read your colonoscopy report without getting overwhelmed

A colonoscopy report can feel technical because it has to communicate precisely with your GP and future endoscopists. Focus first on a few practical lines: whether the caecum was reached, whether the bowel preparation was adequate, how many polyps were removed, where they were found, whether any were left for a second procedure, and what recall interval was recommended. The pathology report then adds the tissue diagnosis. Patients do not need to understand every histology term on day one, but they should understand whether the finding was low-risk, higher-risk or needing further action.

If the recall recommendation is unclear, ask for clarification rather than guessing. A good result letter should tell you when to see your GP, when to expect pathology, and when the next colonoscopy is likely to be due. This is also a useful time to ask whether family members need to know anything. Most isolated small polyps do not mean relatives suddenly need urgent colonoscopy, but advanced polyps, multiple polyps or bowel cancer can change family-history advice.
