What is a Lymph Node Biopsy?
A lymph node biopsy is a procedure in which tissue is removed from one or more lymph nodes for microscopic examination by a pathologist. Lymph nodes are small, bean-shaped structures distributed throughout the body that form part of the immune system. They filter lymphatic fluid and trap bacteria, viruses, and abnormal cells including cancer cells.
When lymph nodes become enlarged (lymphadenopathy), a biopsy may be needed to determine the underlying cause. Three main types of lymph node biopsy are performed:
- Fine Needle Aspiration Cytology (FNAC): A fine needle extracts cells from the lymph node for cytological analysis. Fast and minimally invasive, but provides cells rather than tissue architecture.
- Core needle biopsy (CNB): A larger bore needle (14–18 gauge) takes a tissue core preserving the lymph node architecture — essential for lymphoma subtyping.
- Excisional biopsy: Surgical removal of the entire lymph node — the gold standard for lymphoma diagnosis but requires anaesthesia and an incision.
At Edge Imaging & Diagnostics in Paschim Vihar, Delhi, we perform ultrasound-guided and CT-guided core needle biopsies — providing tissue architecture for definitive lymphoma subtyping and cancer diagnosis with minimal invasiveness.
Why is a Lymph Node Biopsy Done?
A lymph node biopsy is recommended when a lymph node is persistently enlarged or when certain findings raise suspicion for a significant underlying condition:
- Suspected lymphoma: Hodgkin or Non-Hodgkin lymphoma commonly presents as painless lymph node enlargement, particularly in the neck, axilla, or groin.
- Metastatic cancer: When cancer from another site (breast, lung, head and neck, thyroid) spreads to nearby or distant lymph nodes.
- Tuberculosis (TB lymphadenitis): One of the most common causes of cervical lymph node enlargement in India, requiring tissue confirmation for diagnosis and drug sensitivity testing.
- Sarcoidosis: Systemic granulomatous disease that frequently involves mediastinal and hilar lymph nodes.
- Cat scratch disease, fungal infections: Infectious causes of lymphadenopathy requiring culture and sensitivity from biopsy material.
- Unexplained persistent lymphadenopathy: Nodes enlarging for more than 4–6 weeks without obvious infectious cause require tissue diagnosis.
Who Needs a Lymph Node Biopsy?
You may need a lymph node biopsy if you have:
- Lymph nodes enlarged to more than 1 cm that persist for more than 4–6 weeks
- Lymph nodes that are hard, rubbery, fixed, or matted together
- Lymph node enlargement accompanied by fever, night sweats, or unexplained weight loss (B symptoms)
- Lymph node enlargement in a person with a known primary cancer (staging evaluation)
- Abnormal lymph nodes detected on CT scan, PET-CT, or ultrasound
- Suspected tuberculosis with lymph node involvement (scrofula)
- Mediastinal or hilar lymphadenopathy on chest X-ray or CT
Symptoms That May Lead to a Lymph Node Biopsy
- Painless swelling in neck, armpit, or groin lasting more than 4 weeks
- Drenching night sweats
- Unexplained fever lasting several weeks
- Significant unexplained weight loss (more than 10% of body weight)
- Itching all over the body without a skin rash (pruritus)
- Persistent fatigue and reduced exercise tolerance
- Feeling of fullness in the abdomen due to enlarged abdominal lymph nodes
Preparation Before a Lymph Node Biopsy
- Blood tests: Complete blood count and coagulation profile before the procedure.
- Stop blood thinners: Aspirin, warfarin, clopidogrel, and similar drugs should be stopped 5–7 days before the procedure as instructed by your doctor.
- Fasting: Light fasting (2–4 hours) is recommended for a core needle biopsy. Full fasting is required if sedation is planned.
- Documents: Bring your referral letter, recent ultrasound/CT/PET-CT reports, and previous blood test results.
- Imaging guidance selection: Your radiologist will determine whether ultrasound guidance or CT guidance is more appropriate based on the lymph node location.
- Consent form: You will sign an informed consent form explaining the procedure and possible complications.
Step-by-Step Lymph Node Biopsy Procedure
Here is a detailed step-by-step account of an ultrasound-guided lymph node core biopsy at Edge Imaging & Diagnostics in Paschim Vihar, Delhi:
- Patient positioning: Positioned based on lymph node location — typically supine with head turned away for neck nodes, arm raised for axillary nodes.
- Pre-biopsy ultrasound: High-resolution ultrasound identifies the target lymph node, assesses its vascularity with Doppler, and maps the safest needle path avoiding major vessels and nerves.
- Skin preparation: The overlying skin is sterilised with antiseptic and sterile drapes applied.
- Local anaesthesia: Lidocaine is injected from the skin surface to the edge of the lymph node capsule to numb the biopsy tract.
- Needle insertion: A 14–18 gauge core biopsy needle is inserted under real-time ultrasound guidance toward the target lymph node.
- Core sampling: 2–4 core samples are taken from the lymph node, targeting the viable peripheral cortex and avoiding central necrotic areas to maximise diagnostic yield.
- Sample handling: Tissue cores are placed in formalin for histology. Additional cores may be placed in saline for flow cytometry (lymphoma immunophenotyping) or sent for microbiology (TB culture).
- Post-biopsy compression: Gentle pressure is applied to the biopsy site for 5–10 minutes to control any bleeding.
- Dressing applied: A small adhesive dressing is placed over the biopsy site.
- Observation: You rest for 20–30 minutes before discharge.
What Happens After a Lymph Node Biopsy?
- Site care: Keep the biopsy site dry for 24 hours. Change the dressing as instructed.
- Activity: Avoid strenuous activity and heavy lifting for 24–48 hours.
- Pain: Mild soreness at the biopsy site is normal. Paracetamol provides effective relief — avoid aspirin and NSAIDs for 48 hours.
- Swelling: Minor bruising or swelling at the site is expected and resolves within a few days.
- Warning signs: Contact your doctor immediately if you develop fever, increasing pain, swelling, bleeding that does not stop, or breathing difficulties after a neck biopsy.
- Results: Histopathology reports take 5–7 working days. Flow cytometry results take 3–5 days. Microbiology cultures (for TB) take 4–6 weeks.
Risks and Complications of Lymph Node Biopsy
- Bleeding: Minor local haematoma is the most common complication — usually resolves without intervention.
- Infection: Very rare with sterile technique. Managed with antibiotics if it occurs.
- Nerve injury: Extremely rare with ultrasound guidance. The radiologist carefully maps surrounding nerves before sampling.
- Pneumothorax: Relevant only for mediastinal nodes biopsied under CT guidance — risk is minimised with careful technique.
- Inadequate sample: Rarely, insufficient tissue is obtained for diagnosis — a repeat biopsy or surgical excision may then be recommended.
Benefits of Lymph Node Biopsy
- Definitive tissue diagnosis for lymphoma, TB, sarcoidosis, and metastatic cancer
- Avoids unnecessary surgery by providing diagnosis through minimally invasive needle technique
- Enables complete lymphoma immunophenotyping and genetic testing from a single procedure
- Guides staging of primary cancers when lymph node involvement is suspected
- Allows TB culture and drug sensitivity testing for appropriate antibiotic selection
- Same-day outpatient procedure with rapid recovery
Test Accuracy and Reliability
Ultrasound-guided core needle biopsy of accessible lymph nodes achieves a diagnostic accuracy of 85–95% for lymphoma and near 100% for metastatic carcinoma and TB. CT-guided biopsy is used for deep or inaccessible nodes (mediastinal, retroperitoneal, pelvic) with similarly high accuracy. At Edge Imaging & Diagnostics in Paschim Vihar, Delhi, we optimise diagnostic yield by collecting adequate tissue cores, performing appropriate triage (histology, flow cytometry, microbiology), and working with experienced lymphoma and oncology pathologists.

Frequently Asked Questions About Lymph Node Biopsy
1. Is a lymph node biopsy painful?
A lymph node biopsy is performed under local anaesthesia. The anaesthetic injection causes a brief sting. The biopsy itself is typically felt as pressure rather than pain. Most patients tolerate the procedure well as an outpatient.
2. How long does a lymph node biopsy take?
An ultrasound-guided lymph node core biopsy takes approximately 20–30 minutes. Including preparation, local anaesthesia, sampling, and post-procedure observation, plan for about 60–90 minutes at the centre.
3. What is the difference between FNAC and core needle biopsy of a lymph node?
FNAC extracts individual cells using a fine needle — quick but provides limited information, mainly used for cytological screening. Core needle biopsy takes a tissue cylinder preserving lymph node architecture — essential for definitive lymphoma subtyping and immunohistochemistry.
4. How long do lymph node biopsy results take?
Histopathology results take 5–7 working days. Flow cytometry results (for lymphoma) take 3–5 days. Microbiological cultures for TB take 4–6 weeks. Your oncologist or haematologist will discuss results with you at a follow-up appointment.
5. Can lymph node biopsy diagnose lymphoma?
Yes. Core needle biopsy with immunohistochemistry and flow cytometry can diagnose and subtype most lymphomas. In rare complex cases, a surgical excisional biopsy may still be required for full lymphoma classification.
6. Can lymph node biopsy confirm TB?
Yes. Lymph node biopsy can confirm tuberculosis by demonstrating caseating granulomas on histology, positive Ziehl-Neelsen stain for acid-fast bacilli, or positive TB culture and PCR from biopsy material.
7. What size lymph node requires biopsy?
Lymph nodes larger than 1–1.5 cm that persist for more than 4–6 weeks without clear infectious cause warrant further evaluation including biopsy. Nodes with suspicious features on imaging (round shape, loss of fatty hilum, increased vascularity) may require biopsy regardless of size.
8. Is lymph node biopsy safe in the neck?
Yes. With ultrasound guidance, cervical lymph node biopsy is very safe. The radiologist carefully maps the carotid artery, jugular vein, and vagus nerve before sampling to ensure the needle path avoids these important structures.
9. What happens if lymph node biopsy is inconclusive?
If the biopsy returns inconclusive or insufficient material, a repeat core needle biopsy targeting a different node or area, CT-guided biopsy of a deeper node, or surgical excisional lymph node biopsy may be recommended for definitive diagnosis.
