Who is it for?
Lymph node biopsy identifies the cause of enlarged or suspicious nodes in the neck, armpit, groin or abdomen: infection, benign reactive enlargement, lymphoma or spread from another tumor can only be distinguished by tissue examination.
The method follows the suspicion: fine-needle aspiration for cytology, core needle when tissue architecture matters (particularly suspected lymphoma); some cases need surgical excision. The choice is made with the relevant specialties.
How it is done — step by step
Assessment
The target node is examined with ultrasound; the most suspicious, safest sampling point is chosen.
Local anaesthesia
Skin and track are numbed.
Sampling
Samples are taken with a fine or core needle under ultrasound guidance; each pass lasts seconds. Extra material is set aside for special tests (such as flow cytometry) when needed.
Finish
Brief compression and a small dressing; no stitches.
What to expect on the day
Fasting is usually unnecessary; tell us in advance if you take blood thinners.
The visit typically takes 15–30 minutes; after brief observation you return to your day.
Risks and Limitations
Superficial node biopsy is low-risk: mild soreness and bruising are most common; significant bleeding and infection are rare. In vessel-rich regions such as the neck, continuous ultrasound vision protects these structures.
A limit: needle biopsy may not allow definitive classification of some lymphoma types; surgical removal of the whole node may then be required. This possibility is discussed from the start.
Recovery and follow-up
Normal life resumes the same day; site tenderness settles within days.
Results, including any special studies, are usually complete within days to two weeks and are reviewed with your treating physician.

Frequently Asked Questions
Is every enlarged node bad?
No — nodes also enlarge with infections, and most enlargements are benign. Biopsy brings clarity when suspicious features persist.
Fine needle or core?
Cytology may need only a fine needle; core is preferred when architecture matters, as in suspected lymphoma. The choice follows the suspicion and the node’s location.
Is it painful?
Done under local anaesthesia; most patients feel only pressure, and it is over in minutes.
When is the result ready?
Usually within days to two weeks — special studies for lymphoma can extend this slightly.
Will surgical biopsy be needed?
Definitive classification of some lymphomas requires excision of the whole node; needle biopsy is the first and often sufficient step.
Can I return to work the same day?
Yes — after brief observation you can resume your day.
