Lymph node biopsy, ultrasound-guided core biopsy or excisional biopsy of enlarged lymph nodes.
Lymph node biopsy takes tissue for histology from an enlarged or suspicious node. Modern options: ultrasound-guided core biopsy, FNA, or excisional biopsy — for lymphoma diagnosis, metastatic staging, sarcoidosis and infection.
Why patients choose us
- 01
The right hands
We route you to a consultant interventional radiologist or head-and-neck surgeon — whoever your case actually needs.
- 02
Right technique, first time
Core biopsy, FNA or excisional — chosen for the clinical question, not for what the clinic happens to offer.
- 03
Independent, and free
We are paid by no clinic, so the recommendation is impartial and costs you nothing.
Key facts
What every patient should know about lymph node biopsy.
A quick orientation to the technique, the choice between core and excisional biopsy, and how the tissue is handled.
-
What it is
A biopsy of an enlarged or suspicious lymph node — sampling tissue for histology.
-
US-guided core biopsy
Often first-line: image-guided cores from a palpable or ultrasound-visible node.
-
Excisional biopsy
For suspected lymphoma — nodal architecture matters for accurate subtyping.
-
FNA
Fine-needle aspiration is a screening tool for metastatic disease from a known primary.
-
Local anaesthetic day-case
Performed under LA in a day-case setting — home the same afternoon.
-
Handled for full work-up
Sample split for histology, flow cytometry and molecular tests where lymphoma is on the differential.
How it’s done
From consultation to histology — step by step.
The path from first appointment to the pathologist’s report. Most patients are home the same afternoon.
- 01
Consultation and imaging
Review of history, examination and existing ultrasound, CT or PET-CT.
- 02
Coagulation check
Recent bloods (FBC, clotting) and a review of anticoagulant or antiplatelet medication.
- 03
Local anaesthetic
Skin and track infiltrated with lidocaine — the procedure itself is not painful.
- 04
US-guided needle placement
Real-time ultrasound guides the needle to the target node, away from vessels and nerves.
- 05
Multiple cores taken
Several passes with a core-biopsy device — usually three to five cores for adequate tissue.
- 06
Excisional if lymphoma suspected
If lymphoma is on the differential, an intact node is removed surgically to preserve architecture.
- 07
Histology in 7–14 days
Reported by a specialist haematopathologist, with immunohistochemistry and molecular add-ons.
What it shows
The diagnoses a lymph node biopsy can confirm.
From the benign and reassuring to the diagnoses that trigger a specialist pathway — the biopsy tells the story.
-
Reactive lymphadenopathy
Benign, infection-driven node enlargement — the most common answer.
-
Hodgkin lymphoma
Classical or nodular lymphocyte-predominant subtypes, staged and treated by haematology.
-
Non-Hodgkin lymphoma
Wide range of B- and T-cell lymphomas — subtype drives the treatment plan.
-
Metastatic carcinoma
Nodal spread from a known or occult primary — head-and-neck, breast, lung, GI.
-
Sarcoidosis granulomas
Non-caseating granulomas — the tissue diagnosis that unlocks the sarcoidosis pathway.
-
TB granulomas
Caseating granulomas with special stains and TB culture where indicated.
-
Castleman disease
Rare lymphoproliferative disorder — unicentric or multicentric variants.
-
Red flag: high-grade lymphoma — urgent haematology MDT
Aggressive histology triggers same-week haematology review and staging.
Treatment options
What happens after the diagnosis is made.
Every biopsy result — reactive, malignant or granulomatous — has a defined next step. These are the main pathways.
-
Reassurance for reactive nodes
Benign histology, with a plan for re-imaging if the node does not settle.
-
Haematology / oncology MDT
A malignant diagnosis is routed straight into the appropriate specialist MDT.
-
Chemotherapy / immunotherapy
The mainstay of treatment for most lymphomas and disseminated metastatic disease.
-
Radiotherapy for early-stage Hodgkin
Combined-modality treatment for limited-stage classical Hodgkin lymphoma.
-
Sarcoidosis treatment (steroids)
Corticosteroids where organ involvement or symptoms justify treatment.
-
TB pathway
Referral to the local TB service for standard anti-tuberculous therapy and contact tracing.
-
Antibiotics for infection
Targeted antibiotics where a specific infective cause is identified.
-
Structured follow-up
Clinical and imaging surveillance to confirm resolution or detect recurrence.
Red flags
When lymphadenopathy needs urgent attention.
Scenarios where the pathway is expedited or handed to a specialist MDT the same week.
-
High-grade lymphoma
Diffuse large B-cell and other aggressive subtypes — urgent haematology input.
-
Metastatic SCC (head-and-neck)
Squamous cell carcinoma in a neck node triggers head-and-neck MDT and primary search.
-
Rapidly growing node
Rapid, painless enlargement over weeks warrants urgent tissue diagnosis.
-
Constitutional symptoms (B symptoms)
Fever, drenching night sweats or weight loss raise suspicion of lymphoma.
-
HIV-related lymphadenopathy
A distinct differential including HIV-associated lymphoma and opportunistic infection.
-
Post-transplant lymphoproliferative disease
EBV-driven proliferation in transplant recipients — treated by the transplant team.
-
TB with drug resistance
Positive TB with resistance requires specialist infection input and public-health notification.
-
Suspected sarcoma metastasis
Nodal spread from soft-tissue or bone sarcoma — sarcoma MDT pathway.
-
Kikuchi disease differential
Rare histiocytic necrotising lymphadenitis — usually self-limiting, avoids overtreatment.

Frequently asked
Everything we get asked about lymph node biopsy.
Quick answers on core vs excisional biopsy, FNA, pain, results and when the pathway becomes urgent.
-
What does a lymph node biopsy show?
Whether an enlarged node is reactive (benign), infective (such as TB), granulomatous (such as sarcoidosis), or malignant (lymphoma or metastatic cancer). The pathologist reports cell type, immunohistochemistry and, where relevant, molecular findings.
-
Core biopsy or excisional biopsy — which is right?
Ultrasound-guided core biopsy is often first-line and answers most metastatic questions. If lymphoma is on the differential, an excisional (whole-node) biopsy is preferred because lymphoma subtyping depends on preserved nodal architecture.
-
What is an FNA and when is it used?
Fine-needle aspiration collects cells rather than tissue cores. It is a good screening tool for metastatic carcinoma from a known primary, but it is rarely sufficient to diagnose or subtype lymphoma.
-
Is a lymph node biopsy painful?
The skin and track are infiltrated with local anaesthetic, so the procedure itself feels like pressure rather than pain. Excisional biopsy is done under local or general anaesthetic depending on site and patient preference.
-
How long do results take?
Core-biopsy histology is typically reported within 7–14 days, with molecular and immunohistochemistry add-ons taking a little longer. Urgent cases are expedited by the pathology team.
-
When should I see a doctor urgently?
Rapidly enlarging, painless nodes — especially with fever, drenching night sweats or weight loss — need urgent assessment under the two-week-wait pathway. Any sudden airway symptoms are an emergency.

In practice, in London
Why private lymph node biopsy moves differently in London
With lymph node biopsy, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. Public provision for lymph node biopsy is competent but constrained by capacity. Private London clinics tend to have shorter diaries and longer appointment slots, so you get the same specialists with more time. For people who’ve been going round in circles with primary care, that first proper conversation is often what shifts things.
The mechanics are straightforward: a consultant appointment, any tests done at a nearby CQC-registered site, and a written report back within a few days. London’s density of private diagnostics — Marylebone, the City, Chelsea, Canary Wharf — means most patients can find something that fits around work without a cross-town trek. For lymph node biopsy specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
There are a lot of consultants in London who can technically handle lymph node biopsy. Fewer who do it week in, week out for the exact question you’re bringing. We spend most of our time working out which is which — and being straight when a different test or a different specialist would serve you better. Everything runs to CQC, GMC and Royal College standards; the choice is about fit, not floor.
