CION Ameerpet
A swollen lymph node in the neck is common and, in most people, harmless — usually infection or, in our region, tuberculosis. This guide explains the likely causes, the specific red flags that mean a lump needs a biopsy, and how CION assesses a node that will not settle.
Finding a lump in your neck is unsettling, and it is natural to fear the worst. So let's begin with reassurance grounded in fact: the vast majority of swollen lymph nodes in the neck are not cancer. Lymph nodes are small bean-shaped filters that swell when they are working — most often fighting an infection nearby. A swollen lymph node neck lump usually reflects a sore throat, tonsillitis, a dental problem, an ear infection or a passing viral illness.
The most common lump in neck causes are, in rough order of frequency: reactive nodes from infection; tuberculosis of the lymph nodes (a genuinely common cause here in Telangana and Andhra Pradesh); autoimmune conditions; and — much less often — a blood cancer such as lymphoma or a spread from another cancer. In other words, neck gland swelling lymphoma is possible, but it sits low on the list of likely explanations.
That said, some lumps do need proper assessment rather than another course of antibiotics. The rest of this page explains how to tell an ordinary swelling from one that deserves attention, and what happens if a node needs investigating. For a broader view of when a lump could point to a blood cancer, see swollen lymph nodes — when a lump could mean lymphoma.
In India, tuberculosis is one of the most common causes of a persistent swollen neck lymph node — so much so that TB lymphadenitis (often called scrofula) is a leading reason for a lymph-node biopsy in our region. This is exactly why a lump that will not settle should be sampled and tested, not treated with repeated antibiotic courses: a biopsy can distinguish TB, lymphoma and reactive nodes from one another. (Source: World Health Organization Global TB Report; India accounts for the largest share of the world's TB burden.)
Most neck lumps settle on their own. But a swollen node deserves a proper look — and often a biopsy rather than more antibiotics — if it shows any of these features.
A single red flag does not mean cancer — but it does mean the lump should be examined properly. The rule to remember: a painless node that has not settled in 3–4 weeks needs a biopsy, not another antibiotic prescription. Unsure how long is too long?

You cannot reliably diagnose a lump by feel alone — persistence matters more than any single feature — but this general guide shows the patterns doctors look for.
| Feature | More likely infection / reactive | Warrants closer review |
|---|---|---|
| Pain | Often tender or sore | Usually painless |
| Duration | Settles within 2–3 weeks | Persists beyond 3–4 weeks |
| Texture | Soft to slightly firm, movable | Hard, rubbery or fixed |
| Onset | With an obvious illness (sore throat, cold) | Appears without a clear infection |
| Other signs | Fever that resolves with the illness | Night sweats, weight loss, ongoing fever (B symptoms) |
This table is a general guide only and cannot replace a clinical examination. TB nodes can sit between these columns — firm, sometimes matted and slow to settle — which is why a persistent lump should be sampled. If you are asking yourself "do I have lymphoma?", this guide on separating infection from red flags may help.

If a node has persisted beyond 3–4 weeks, sits above the collarbone, or comes with fever, night sweats or weight loss, CION's team can assess it properly — biopsy, TB testing and, if needed, lymphoma care all in one place.
When a lump does not settle, the goal is to find out why — and, critically, to rule TB and lymphoma in or out. CION delivers the imaging, biopsy coordination, pathology, molecular testing and staging directly, so you are not sent from place to place.
A specialist examines the node — its size, texture, whether it is movable, and whether other node groups (armpit, groin, above the collarbone) are involved — and asks about how long it has been there, recent infections, and any B symptoms. This alone often points strongly to a cause.
An ultrasound shows the node's shape and internal structure and helps decide whether and how to sample it. Blood tests may be added to look for infection or other causes.
For a persistent or suspicious node, a biopsy is the definitive test. A fine-needle sample is often taken first; if lymphoma is suspected, an excision (whole-node) biopsy is preferred because a pathologist needs to examine the node's whole architecture, not just scattered cells. The same tissue is tested for TB. When lymphoma is the question, molecular markers such as CD20 and CD30 are examined to characterise the type. This is why a lump that outlasts 3–4 weeks should be sampled — telling TB from lymphoma is done on tissue, not on a scan.
If a biopsy confirms lymphoma, staging follows with a PET-CT and, in some cases, a bone-marrow examination, so the team knows exactly where the disease is before planning treatment. Every case is reviewed at a multidisciplinary tumour board.
It is worth repeating: for most people a swollen neck node is not lymphoma. But if a biopsy does confirm it, the outlook is often far better than people fear, and treatment is highly effective for many types. Lymphoma is broadly divided into Hodgkin and non-Hodgkin types, each with its own treatment path.
Published survival figures vary by type and stage: for example, Hodgkin lymphoma is associated with roughly 80–90% five-year survival in many published series, while diffuse large B-cell lymphoma (DLBCL), a common aggressive non-Hodgkin type, is associated with roughly 60–70% — figures that continue to improve with modern therapy. These are population averages; your own outlook depends on the exact subtype, stage and individual factors, so figures vary by individual. (Survival ranges as summarised in published series and reflected in NCCN and ESMO guidance.)
Treatment is tailored to the subtype and stage and may include chemotherapy, antibody (immunotherapy) treatment such as an anti-CD20 monoclonal antibody, targeted therapy, radiation (IMRT), or careful monitoring (watch-and-wait) for slow-growing types — all delivered directly by CION. Specific drug regimens are decided by your specialist; you can read how the pathway works on our Lymphoma Treatment in Hyderabad page. Specialised procedures such as stem-cell transplant are coordinated through accredited partner facilities when they are needed.
The lymph nodes in the neck are among the most common places lymphoma is first noticed — a painless, persistent swelling being the classic presentation. But the same location is far more often affected by ordinary infection or TB. That overlap is precisely why guidelines recommend biopsy over repeated antibiotics for a node that persists beyond 3–4 weeks — the tissue tells doctors which of these it is. (Source: assessment principles reflected in NCCN and ESMO lymphoma guidelines.)

Start Your Story. Book Free Consultation.The great majority of neck lumps are reactive nodes responding to a nearby infection — a sore throat, tonsillitis, a dental abscess, an ear infection or a viral illness. These usually appear over a day or two, may be tender, and settle within two to three weeks as the infection clears. In Telangana and Andhra Pradesh, tuberculosis (TB) of the lymph nodes is also a genuinely common cause and can produce a firm, sometimes matted swelling that persists. Less often, a swollen node reflects an autoimmune condition or a blood cancer such as lymphoma. Because infection is far more likely than cancer, a new swollen node is usually watched first — but one that does not settle deserves proper assessment.
Most swollen glands are harmless, but certain features are red flags that warrant review rather than another course of antibiotics: a painless node that persists beyond 3–4 weeks; a node that keeps growing; a hard, rubbery or fixed lump; swelling above the collarbone; nodes at several sites at once; or a lump alongside B symptoms — unexplained fever, drenching night sweats or unintended weight loss. Any of these should prompt a clinical examination and, where needed, a biopsy. See our detailed guide on how long is too long for a swollen node, or book a free consultation if you are unsure.
It is not always possible to tell by feel alone, which is why persistence matters more than any single feature. As a rough guide, infection-related nodes tend to be tender, soft or slightly firm, movable, and appear with an obvious illness, then shrink within a few weeks. Nodes that raise more concern tend to be painless, hard or rubbery, fixed to deeper tissue, larger than about 2 cm, and steadily enlarging. TB nodes can sit in between — firm, sometimes matted, and slow to settle. Because overlap is common, a node that has not resolved in 3–4 weeks should be examined. Read more on whether lymphoma lumps are hard, soft or movable.
Yes — and in our region this is important. TB of the neck lymph nodes (often called scrofula or cervical lymphadenitis) is a common cause of a persistent neck swelling in Telangana and Andhra Pradesh. It can produce a firm or matted lump, sometimes with low-grade fever, weight loss or night sweats — features that overlap with lymphoma. The two are distinguished by tests: a fine-needle sample or a biopsy, along with TB-specific tests. This is exactly why a persistent node should be sampled rather than repeatedly treated with antibiotics. Our dedicated guide explains how doctors tell TB apart from lymphoma.
Assessment starts with a clinical examination and history, often followed by an ultrasound of the neck to look at the node's size, shape and internal structure. Blood tests may be done to check for infection or other causes. The definitive step for a persistent or suspicious node is a biopsy — usually a fine-needle sample first, and an excision (core or whole-node) biopsy if lymphoma is suspected, because the node's architecture must be examined. If lymphoma is confirmed, staging with a PET-CT and, in some cases, a bone-marrow exam follows. CION delivers biopsy coordination, pathology, molecular marker testing and staging directly. Learn more about when a swollen node could mean lymphoma.
A lump above the collarbone (supraclavicular) needs prompt review because this location is more often linked to serious causes. Also treat as urgent: a rapidly enlarging node; a node with breathing or swallowing difficulty; a hard fixed mass; or a neck lump together with drenching night sweats, unexplained weight loss or persistent fever. These do not mean you have cancer — most causes are still benign — but they should not be watched indefinitely. Talk to a CION specialist if any of these apply to you.
If a biopsy confirms lymphoma, the next steps are staging and a personalised plan. CION's haematology and oncology team completes staging (PET-CT and, where needed, a bone-marrow exam), confirms the subtype and reviews every case at a multidisciplinary tumour board before treatment begins. Depending on the type and stage, treatment may involve chemotherapy, antibody (immunotherapy) treatment, targeted therapy, radiation (IMRT) or careful monitoring (watch-and-wait) — all delivered directly by CION; specialised procedures such as stem-cell transplant are coordinated through accredited partner facilities when needed.
