Understanding your biopsy

Who Performs — Your Biopsy?

The doctor who takes a biopsy is usually not your oncologist. It depends on where in your body the tissue needs to come from — and knowing what to expect can make the referral feel less alarming.

  • Different specialists for different sites — A radiologist, surgeon or endoscopist may each be the right person depending on where the lesion is.
  • Your oncologist coordinates — Your cancer doctor orders the biopsy and interprets the result, but does not usually perform the procedure.
  • A pathologist reads the result — The tissue analysis is done in a laboratory by a pathologist, who issues a written report your oncologist uses.
  • Experience shapes sample quality — A skilled operator is more likely to obtain enough tissue to give the pathologist a clear answer.

The doctor who takes a biopsy depends on where the tissue is coming from. A radiologist uses imaging to guide a needle to a deep mass. A surgeon removes tissue directly. An endoscopist takes samples from inside the digestive tract. Your oncologist orders the biopsy and coordinates whoever is best placed to perform it.

Which doctor is responsible for taking the biopsy?

The doctor who performs a biopsy is usually a different person from your oncologist. Your oncologist decides that a biopsy is needed and will interpret the result — but the procedure itself is done by a specialist chosen for that particular site.

Which specialist depends on where in your body the tissue needs to come from. A lump close to the surface of the skin is reached differently from a mass deep inside the chest or abdomen.

The result is always read by a pathologist — a doctor trained to examine tissue under a microscope. You will not usually meet the pathologist. Their written report is what your oncologist uses to make clinical decisions.

Which specialist performs which type of biopsy?

SpecialistHow they reach the tissueCommon sites
Interventional radiologistNeedle guided by CT scan or ultrasoundLung, liver, kidney, deep lymph nodes, abdominal masses
SurgeonSmall cut or keyhole (laparoscopic) procedureLymph nodes, breast, thyroid, soft tissue
EndoscopistFlexible camera through mouth or rectumOesophagus, stomach, bowel, airway
Dermatologist or skin specialistSmall incision under local anaestheticSkin lesions

Does it matter how experienced the doctor is?

Experience does affect the quality of the sample. A skilled operator is more likely to reach the right area in fewer passes, which means less discomfort for you and a better chance of getting tissue the pathologist can work with.

A sample that is too small or taken from the wrong area can be inconclusive, meaning a repeat procedure may be needed. This is one reason biopsy referrals at dedicated cancer centres are handled by teams who perform these procedures regularly.

It is reasonable to ask who will do your biopsy and how often they perform that specific type of procedure.

Terms you may hear

Interventional radiologist
A doctor who uses imaging — ultrasound, CT or MRI — to guide instruments to an exact point inside the body without open surgery.
Pathologist
The doctor who examines biopsy tissue under a microscope and writes the report. Their finding tells your oncologist whether cancer cells are present and what type they are.
Endoscopist
A specialist — usually a gastroenterologist or trained surgeon — who uses a flexible camera to look inside the digestive tract and take samples from the lining.
Core needle biopsy
A biopsy where a hollow needle removes a thin cylinder of tissue. This gives the pathologist more material to work with than a fine-needle test.
Fine-needle aspiration (FNA)
A biopsy using a very thin needle to draw out individual cells. Faster and more comfortable, but may give less information depending on the site.

Did you know?

The pathologist who reads your biopsy is usually not present when the sample is taken. The tissue travels to the laboratory preserved in formalin, where it is sliced thin, stained and examined under a microscope before a written report goes to your oncologist.

Questions people ask about who performs the biopsy

Will my oncologist be there when the biopsy is done?

Usually not. Your oncologist's role is to decide that a biopsy is needed, explain what it will look for, and discuss the result with you when it comes back. The procedure itself is done by the specialist best suited to the site — an interventional radiologist for a deep lesion, a surgeon for lymph node tissue, an endoscopist for gut samples. You may briefly meet the performing specialist beforehand, but your oncologist remains the one who guides your overall care.

Who tells me the result?

Your oncologist tells you the result — not the radiologist or surgeon who took the sample, and not the pathologist who examined it. The pathologist's report goes to your oncologist, who reviews it in the context of your full clinical picture: your scans, your symptoms and your history. If you have a follow-up appointment scheduled, that is usually when the result is explained to you in full.

What if the sample does not give a clear result?

This does happen, and it is more common with some biopsy sites than others. The pathologist may report that there was insufficient material, or that the tissue did not include a representative area of the lesion. In that situation your oncologist will discuss whether a repeat biopsy is needed and whether a different technique would be more reliable. An inconclusive result is not the same as a negative result — it means the question has not yet been answered.

Is a biopsy done in an operation theatre?

Not always. Where the biopsy is done depends on the technique. An image-guided needle biopsy is often done in a radiology suite and may require only a local anaesthetic to numb the area. An endoscopic biopsy is done in an endoscopy unit. A surgical biopsy — where tissue is removed through a cut — is done in an operation theatre, sometimes under sedation or general anaesthetic. Your team will explain what is planned before you go.

Can I ask who specifically will perform the procedure?

Yes, and it is a reasonable question. At dedicated cancer centres, image-guided biopsies are typically performed by interventional radiologists who do this as a core part of their work. If you have concerns about who will be performing the biopsy, raise them with your oncologist before the appointment rather than on the day — there is usually time to address those concerns if they are raised early.

Common questions

Frequently asked questions

Is the doctor who does my biopsy part of my cancer team?

The specialist who performs the biopsy is part of the wider team caring for you, but they are not usually the doctor managing your ongoing cancer treatment. Your oncologist coordinates the referral and will be the one who explains the result. The radiologist, surgeon or endoscopist who takes the sample is a specialist in that procedure — their job is to obtain the best quality tissue safely, and your oncologist's job is to interpret what it means for your care.

What does a pathologist do with my biopsy sample?

The pathologist receives the tissue in a preservative solution and processes it in the laboratory — slicing it very thin, staining the cells and examining them under a microscope. They describe what the cells look like and whether they appear abnormal. This report is the document your oncologist uses to confirm or rule out cancer and plan the next step. The pathologist does not meet you or tell you the result directly.

Will I be awake when the biopsy is done?

For most image-guided needle biopsies, yes — you will be awake, with the area numbed by a local anaesthetic. You may feel pressure but should not feel sharp pain. For a surgical biopsy or a procedure that requires you to remain completely still for a long time, sedation or general anaesthetic may be used. Your team will tell you in advance what is planned and what you need to do to prepare.

How long does a biopsy result take?

Most routine biopsy results are available within one to two weeks of the sample being taken. Some specialist tests — such as molecular or genetic analysis run alongside the standard examination — can take a little longer. Ask your team when the result is expected and when your follow-up appointment is scheduled, so you are not waiting without a clear timeline.

What does it mean if my biopsy result is inconclusive?

An inconclusive result means the pathologist could not give a definitive answer from that sample — usually because there was not enough tissue, or the tissue came from the wrong area. It is not the same as a clear negative result. Your oncologist will explain what happened and whether a repeat biopsy is recommended, and if so, whether a different approach would give a better result. This is a frustrating but not uncommon situation.

Does a biopsy confirm cancer?

A biopsy is the question, not the verdict. It gives the pathologist tissue to examine — and the result may confirm cancer, rule it out, or show something else entirely, such as inflammation or a benign growth. In a small number of cases the sample is insufficient or the result is borderline, and further testing is needed. Your oncologist will explain what the result means for you specifically once the report is available.
