Polyp removal and follow-up

What happens when polyps are found at colonoscopy - removal techniques, recovery, histology and UK surveillance intervals.

At a glance

  • Preparation

    Nothing extra is needed on the day - polypectomy happens within the colonoscopy - but anticoagulant plans made at pre-assessment matter for larger removals.

  • What happens during the test

    Small polyps are removed with cold snare or forceps in seconds; larger ones are lifted with fluid injection and removed with a diathermy snare, occasionally with clips placed afterwards.

  • Results timeline

    Histology classifies each polyp within about two weeks, which determines the surveillance recommendation.

  • Specialist follow-up

    UK guidelines set the next colonoscopy interval - commonly three years for higher-risk findings, with many low-risk patients simply returning to routine screening.

What this test is and when it is recommended

Removing polyps is the point of colonoscopy: adenomas and serrated polyps are the precursors of most bowel cancers, and taking them out interrupts that sequence. Removal is painless and usually adds only minutes to the procedure. Follow-up depends on what the pathologist finds - the number, size and grade of the polyps - not on how they looked down the camera. A small delayed-bleeding risk exists for about two weeks after larger removals, which is why strenuous exertion and long-haul travel are briefly restricted.

How to access it

Polypectomy is included within private colonoscopy pathways booked via GP referral or self-pay, with surveillance scheduling handled by the specialist. NHS waiting lists for diagnostics are often long, while private appointments are typically available within days to around two weeks. Costs vary by provider.

Frequently asked

Common questions about Polyp removal and follow-up.

Quick, plain-English answers to what people ask us most.

  • What is Polyp removal and follow-up?

    Polyp removal and follow-up is a blood test that measures a specific substance or marker in your blood, giving your doctor useful information about how a particular system in your body is functioning. It is one of many tools used alongside your symptoms and history to build a fuller clinical picture. Your doctor can explain exactly why it is relevant in your case.

  • Why would a doctor order Polyp removal and follow-up?

    This test is typically requested to investigate specific symptoms, monitor an existing condition, or check for a deficiency or imbalance that could explain how you are feeling. It may also be used as part of a broader panel of related tests rather than in isolation. The result helps guide whether further tests, treatment, or simple monitoring is appropriate.

  • Do I need to prepare for this test?

    Some blood tests require fasting, a specific time of day, or pausing certain medications or supplements beforehand, while others need no special preparation at all. You will usually be told what applies to your specific test when it is booked. If you are unsure, it is worth checking with the clinic or lab in advance.

  • What happens during the test?

    A small blood sample is taken, usually from a vein in your arm, in a process that takes only a few minutes. It is generally straightforward and similar to any other routine blood draw. You can normally return to your usual activities straight afterwards.

  • Does this test hurt or carry any risks?

    A standard blood draw involves brief discomfort from the needle but is otherwise low-risk. Minor bruising at the site is the most common side effect and usually settles quickly. Let the person taking your sample know if you have a needle phobia or have had problems with blood tests before, as they can help make it more comfortable.

  • How long do results take?

    Results are typically available within a few days, though turnaround can vary depending on the specific test and laboratory used. You will usually be told when and how to expect your results at the time of testing. More specialised tests may occasionally take longer.

  • What do abnormal results mean, and what happens next?

    An abnormal result can have several possible explanations, from common and benign causes to conditions that need further assessment, and is best interpreted by a doctor alongside your symptoms and history. Depending on the finding, next steps might include repeating the test, further investigation, or referral to a specialist. Try not to draw firm conclusions from a number alone before speaking to a clinician.

  • Is this test available on the NHS, or is it better to go private?

    This test can often be arranged privately within days, with results reviewed by a specialist, whereas routine NHS access may depend on your GP agreeing it is clinically indicated and can involve a longer wait. Cost for private testing varies by provider. Many people choose the private route for speed and convenience, particularly if they are self-funding for reassurance rather than an urgent clinical concern.

  • Is this test accurate and reliable?

    Blood tests like this are well established and generally reliable when carried out by an accredited laboratory. Results can occasionally be affected by factors such as timing, recent illness, medication, or hydration, which is why doctors interpret a single result in context rather than in isolation. If a result seems unexpected, repeating the test is sometimes recommended.

  • How do I book this test privately, and how quickly can I be seen?

    You can typically book privately with or without a GP referral, and appointments, including blood draw and results review, are often available within a few days. A doctor will explain what your result means and advise on any next steps.
