Inconclusive biopsy

Second Biopsy Also Inconclusive: — What Comes Next

Two inconclusive biopsies feel like two dead ends. They are the signal that this case needs a different kind of review — one where specialists from several disciplines look at all the evidence together and agree on a path forward.

Medically reviewed by Dr. Mohammed Imaduddin, Surgical Oncologist, MBBS · MS (General Surgery) · M.Ch (Surgical Oncology) · Last reviewed September 2026

  • Two unclear results are not the end — They shift the question to a multidisciplinary team who can weigh all the evidence together.
  • A tumour board is the right next step — Oncologists, pathologists, radiologists and surgeons review your case together and agree on a plan.
  • There are real options beyond more sampling — Watching closely or treating on available evidence may be the more appropriate path for your situation.
  • You can ask for this review directly — If a board review has not been offered, it is reasonable to ask your oncologist whether one is appropriate.

Two inconclusive biopsies do not mean you are out of options. They mean the question has moved beyond sampling alone. A multidisciplinary tumour board — oncologists, radiologists, pathologists and surgeons reviewing together — decides whether a different sampling method, close monitoring, or treatment based on the available evidence is the right path.

What are the options when two biopsies give no clear answer?

Try again with a different methodWatch closely with imagingTreat on available evidence
When it fitsA different site or technique was not tried before, and the team believes it would produce a usable sampleThe lesion is judged low enough risk that meaningful change would be detectable in time to act onThe clinical picture is strong enough to act on, or waiting itself would be harmful
What it does not meanA guaranteed result — tumour biology or access may still limit what any sample showsDoing nothing — it is active surveillance with defined triggers for action, not indefinite postponementGuessing — it is a joint decision based on imaging, clinical history, and partial pathology
What to askWhy would this attempt succeed where the others did not?What change triggers action, and how often will imaging happen?What is the reasoning, and what changes the plan if response is not as expected?

What should you bring to the tumour board review?

  • All biopsy reports, including the pathologist's comments on sample adequacy
  • All imaging from the start — original scans, not just the printed reports
  • A written summary of your symptoms and how they have changed over time
  • All current medicines and any other medical conditions
  • Contact details for every doctor involved in your care so far
  • Your own written list of questions to give your oncologist before the meeting

What does a tumour board actually do with a case like this?

A multidisciplinary tumour board — also called an MDT or tumour board conference — is a meeting where specialists from different fields review a case together and reach a shared decision. For a repeatedly inconclusive biopsy, this is the appropriate next step.

The pathologist re-examines the slides. The radiologist presents the imaging in detail. The surgeon, oncologist and sometimes an interventional radiologist discuss whether further sampling is feasible and what it would realistically show. The group agrees on what the evidence as a whole suggests.

The outcome is a documented, collective clinical judgement — including a clear record of what remains uncertain and what new information would change the plan.

Is it safer to watch and wait, or to treat without a confirmed diagnosis?

Neither is automatically safer. For some presentations, close monitoring is the more conservative and appropriate choice. For others, the risk of waiting outweighs the risk of acting on incomplete information.

The tumour board weighs both. They consider how likely the lesion is to be malignant based on everything available, what the consequences of delay would be, and what the treatment plan would look like in either case.

If you are being asked to make this decision without a board review having taken place, it is reasonable to ask for one first.

What else do families ask at this point?

Should we try a third biopsy?

Possibly, but only if there is a specific reason to think it would succeed where the previous two did not — a different site to sample, a different technique that was not used, or new imaging showing a more accessible area. Repeating the same approach in the same location is unlikely to produce a different result. The tumour board is best placed to answer this, because they can review exactly why the first two samples were inadequate and whether a genuinely different approach changes the odds of a usable result.

What does treating on available evidence actually mean?

It means using the full picture — imaging appearance, how the lesion has behaved over time, your symptoms, clinical history, and whatever the pathology did show, even if not conclusive — to make a treatment recommendation. This happens more often than people realise, particularly for lesions in hard-to-sample locations or tumours that are heterogeneous. The treatment chosen is one the team believes fits the most likely diagnosis. Your oncologist should be able to explain the reasoning clearly, and you should feel able to ask until you understand it.

Can we get a second opinion on the pathology slides?

Yes, and it is reasonable to ask. A specialist pathologist — particularly one with expertise in that tissue type — may give a more specific interpretation, or may confirm that the sample genuinely cannot be characterised further. This does not require a new biopsy. It means sending the existing glass slides and tissue blocks to another laboratory. Ask your oncologist to arrange a specialist review, or ask whether referral to a centre with subspecialty pathology is the right step for your case.

What if we disagree with the board's recommendation?

You are entitled to a second opinion, and asking for one is not a rejection of your current team. A review at a different centre — particularly one with specific expertise in your tumour type — can confirm the recommendation or offer a different perspective. What matters is that the decision you eventually agree to is one you understand and have consented to. Your oncologist should be able to help arrange a referral, and asking does not mean you are being difficult or ungrateful.

Did you know?

Inconclusive biopsies are more common in certain tumour types — including some lymphomas, sarcomas, and lesions in deep or poorly accessible locations.

A specialist review of the existing pathology slides, not just a repeat biopsy, is a legitimate and often underused next step in these situations.

Common questions

Frequently asked questions

Is it normal to have two inconclusive biopsies?

It is uncommon but not rare, particularly for tumours that are heterogeneous, necrotic, or in locations that are difficult to sample safely. Some tumour types — certain lymphomas, sarcomas, and deep abdominal or thoracic lesions — have higher rates of inadequate sampling. Two inconclusive results mean the lesion has been genuinely difficult to characterise from the samples taken. A tumour board review is the appropriate response, because the combined clinical picture may point more clearly than any single biopsy result.

Can a liquid biopsy help when tissue biopsies have been inconclusive?

Sometimes. A liquid biopsy analyses circulating tumour DNA from a blood sample rather than from the tumour itself, and can in some cases identify a tumour type when tissue sampling has failed. Its usefulness depends on the cancer type being considered and whether the tumour sheds enough DNA into the bloodstream to be reliably detected. It is not a universal solution. Ask your oncologist directly whether a liquid biopsy has been considered for your situation and what it would or would not add to the picture.

Will we ever get a definitive diagnosis?

Not always, and that is genuinely difficult to accept. For some lesions in difficult locations, the risks of further sampling outweigh the benefit of a confirmed tissue diagnosis. In those situations, treatment is based on the best available evidence, and the plan is reviewed as new information emerges — including from how the lesion responds to treatment. Your oncologist should explain what is known, what remains uncertain, and what would change the plan if the lesion behaves differently than expected.

Does CION have multidisciplinary tumour board reviews?

Yes. Multidisciplinary board reviews are part of how complex cases are managed across CION's network. If your case has not yet been referred to a tumour board, ask your oncologist whether it should be. If you are coming to a CION centre for the first time, bring all previous biopsy reports, imaging, and clinical records so the board has the full picture from the start.

How long does a tumour board review take to arrange?

Most multidisciplinary boards meet weekly or fortnightly. Your case may be presented at the next scheduled meeting after referral, which can mean a wait of a few days to two weeks depending on the centre. If your team considers the situation urgent, they can request a faster review or seek specialist advice informally in the interim. If you are not sure when your case is being reviewed or what the outcome was, ask your oncologist directly — you should have a clear answer within a working day.

Should we seek a review at a different hospital if the same team has been involved throughout?

If the same group of specialists has been involved from the beginning, a review at a different centre — particularly one with subspecialty expertise in the tumour type being considered — can provide a genuinely independent perspective. This is a legitimate step and your team should be able to help arrange it. Bring all previous biopsies, pathology slides and blocks, all imaging, and a clinical summary. Being clear that you want an independent view rather than just a confirmation is a reasonable thing to ask for.
