Swollen glands in many places: finding the cause | CION Cancer Clinics
Swollen lymph nodes in two or more parts of the body are most often caused by a virus, TB, HIV or an immune condition, and less often by lymphoma or leukaemia. The workup follows an order: examination, blood tests, a chest X-ray or ultrasound, and a biopsy if the cause is still unclear. This page explains each step and the signs that make it urgent. At CION Cancer Clinics, our haematologist reviews abnormal blood reports with you, orders only the tests that answer your question and explains each result plainly.

The short answer
What does generalised lymphadenopathy mean, and is it serious?
Generalised lymphadenopathy means swollen lymph nodes (the small bean-shaped glands that filter infection) in two or more separate parts of the body, such as the neck and the armpits. Most often the cause is an infection or an immune condition, and a set of simple tests usually points to it within a few visits.
Why it is looked at differently from one swollen gland
A single tender gland during a sore throat is the body doing its job. When glands are enlarged in several places at once, the cause is usually something affecting the whole body. Less often it is a blood cancer such as lymphoma or chronic lymphocytic leukaemia.
What your doctor is weighing up first
Your doctor will ask how long the glands have been there, whether they are growing, and whether you have fevers, night sweats or weight loss. They will feel every group of nodes, the liver and the spleen. Soft, tender, mobile glands with a recent illness point one way. Firm, painless glands that keep growing point another.
No blood test or scan can tell from outside exactly what is inside a node. When the picture stays unclear, a biopsy (a small tissue sample) settles it.The usual causes
What causes swollen glands in several places at once?
The causes fall into a few groups. Your history and the first blood tests usually show which group you are in.
Infections
Viral illnesses are the commonest cause, and the glands settle as you recover. In India, TB is always on the list, even without a cough.
Often seen with
- Glandular fever and other viruses
- TB
- HIV
- Toxoplasmosis, often from undercooked meat or cat litter
Immune conditions
When the immune system is overactive, glands swell with it. Joint pain, rashes, mouth ulcers or dry eyes are clues your doctor will ask about.
Examples
- Lupus
- Rheumatoid arthritis
- Sarcoidosis
Medicines
A few medicines, such as phenytoin for fits and allopurinol for gout, can cause swollen glands, sometimes with a rash and fever. Keep taking your medicines and tell the doctor everything you take, so they can judge this.
Blood cancers
Lymphoma and some leukaemias start in the cells that live in lymph nodes. These are a minority of cases, but they are the reason painless, growing glands are never simply watched for months.
Cancers that spread from elsewhere usually cause glands in one area, not all over.Not sure whether this applies to you?

When this cannot wait for an appointment
If swollen glands come with new breathlessness, noisy breathing, swelling of the face or neck that is worse on lying down, or a high fever with shivering and confusion, go to the nearest emergency department today or call 108. Large glands in the chest can press on the airway or a main vein. Do not wait for the biopsy date, and take your reports with you.
The workup
Which tests are done, and in what order?
-
History and a full examination
The doctor checks the neck, collarbones, armpits and groin, and feels for a large liver or spleen. They ask about travel, contact with TB, sexual health, new medicines and any fevers, sweats or weight loss.
-
First blood tests
A complete blood count with a smear, where a trained person looks at your cells under a microscope. ESR or CRP for inflammation, LDH, liver and kidney tests, and tests for HIV, hepatitis B and C and glandular fever. An ANA test is added if an immune condition is suspected.
-
Imaging
A chest X-ray looks for TB and glands in the chest. An ultrasound of the neck or abdomen shows the shape and inside of the nodes. A CT scan is used when glands deep inside the body need mapping.
-
A short period of watching, if it fits
If the glands are soft, the tests point to a recent infection and there are no warning signs, a recheck after a few weeks is reasonable. This does not suit glands that are hard, growing or come with sweats and weight loss.
-
Biopsy of the most suitable node
When the cause is still unclear, the usual choice is to remove a whole node, or take a thick core of tissue. The sample is tested for TB and looked at for lymphoma in the same sitting.

On your report
What do the words on the report mean?
- Reactive lymphadenopathy
- The node looks like a normal gland responding to infection or inflammation. It is reassuring, but the cause still needs naming.
- FNAC
- Fine needle aspiration cytology: a thin needle draws out loose cells. It is useful for TB, but often too small a sample to rule out lymphoma.
- Excision biopsy
- Removal of a whole node under a local or short general anaesthetic, so the pathologist sees how the gland is built.
- Granuloma
- A cluster of immune cells seen in TB, sarcoidosis and a few other conditions.
- Flow cytometry
- A lab test that sorts cells by the markers on their surface. It helps spot leukaemia or lymphoma cells in blood or tissue.
- B symptoms
- Fevers, drenching night sweats and weight loss you cannot explain. They make a biopsy more urgent.
Commonly believed
What do families often get wrong about swollen glands?
"It is surely TB, so let us start the TB tablets."
TB is common, but lymphoma can look very similar from the outside. Starting TB treatment without proof can delay the right diagnosis for months. Ask for the tissue to be tested for TB before treatment begins.
"A painless gland is harmless. Painful ones are the
worry."
It is often the other way round. Tender glands usually come with infection. Glands that are painless, firm and slowly growing are the ones that most need a biopsy.
"The needle test was normal, so it cannot be
cancer."
A needle sample collects scattered cells, not the structure of the gland. If the glands are still there or still growing, a normal FNAC does not close the question. Your doctor may still advise a full node biopsy.
"A course of steroids made the glands go down, so we
are fine."
Steroids can shrink lymphoma for a while and blur a later biopsy. If the glands have not been diagnosed yet, ask the doctor whether steroids can wait until tissue has been taken. Do not stop a medicine you have been prescribed on your own.
Being straight with you
What can this page not tell you, and what should you do next?
This page cannot tell you what is causing your glands. The same swelling can come from a passing virus or from lymphoma, and only your examination, your blood results and, when needed, a biopsy can separate them. A list of causes is not a diagnosis.
Who needs a haematologist
Most people with generalised swollen glands are looked after by a general physician. A haematologist is the right next step if your blood count shows abnormal white cells, if the spleen is enlarged, if a biopsy suggests lymphoma, or if glands keep growing without an answer. At CION, Dr. Basudev Pokhrel and the haematology team review the reports, present the case to a tumour board and coordinate any biopsy or scan with a qualified centre.
What to bring and what to ask
Bring every blood report, scan and biopsy slide or block you have, and a list of all medicines. Ask whether the tissue will be tested for both TB and lymphoma, and what the plan is if the first result is unclear.
Reference ranges differ between laboratories. A single blood result is always read alongside your symptoms and repeat tests.Questions we are asked
Common questions about swollen glands in many places
How many areas count as generalised?
Doctors use the word when swollen lymph nodes are found in two or more areas that are not next to each other, such as the neck and the groin. Glands in one area only are called localised. The difference matters because it changes which causes are most likely and which tests come first.
Does generalised lymphadenopathy mean cancer?
Usually not. Infections, TB and immune conditions cause most cases. Lymphoma and leukaemia are possible, which is why glands that stay, grow or come with night sweats and weight loss are never left without a clear answer. Treat it as something to finish testing, not something to fear or ignore.
Can a blood test alone tell us the cause?
Sometimes. A positive test for glandular fever or HIV, or leukaemia cells seen on the blood smear, can give the answer. Often the blood tests only narrow the list. When they do not explain the glands, a biopsy of a node is still needed to be sure.
Why did the doctor ask for a whole node instead of a needle test?
Lymphoma is diagnosed by looking at how the whole gland is arranged, not just at loose cells. A needle sample can miss this. Removing a whole node, or taking a thick core, gives the pathologist enough tissue for special stains and TB tests in one go, which often saves a second procedure.
Is a PET-CT needed to find the cause?
Not usually at the start. A chest X-ray and an ultrasound, sometimes a CT, are enough to map the glands. A PET-CT is mainly used after a lymphoma diagnosis to see where it has spread, or to choose the most active node to sample when the picture is unclear.
My child has swollen glands in the neck and armpits. Should I worry?
Children get swollen glands with ordinary infections far more often than adults. Still, see a paediatrician if the glands are hard, keep growing, or come with pale skin, bruising, bone pain, fevers or weight loss. Those signs need a blood count without delay.
Can we wait and watch instead of doing a biopsy?
Sometimes, for a short time, when the glands are soft, the tests suggest a recent infection and there are no warning signs. Watching does not suit hard or growing glands, or glands with night sweats and weight loss. Agree a recheck date with your doctor before you leave the clinic.
Are these tests covered by Aarogyasri or insurance?
Coverage depends on your scheme and on whether a diagnosis has been made. Aarogyasri, PM-JAY, CGHS, ECHS, EHS and cashless insurance cover many cancer workups, but rules change, so check your current entitlement. Call the helpline with your card details and we will help you check before you travel.
