Swollen glands and spleen check (Assessment of lymphadenopathy and splenomegaly)
A specialist check to find out why a lymph node (gland) or the spleen is enlarged, and whether any further tests are needed.
✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review
In short
- It is a step-by-step check to find the cause of a swollen gland or spleen, not a treatment.
- Most swollen glands are from infection and settle, but persistent, usually not painful or widespread swelling needs assessing.
- Blood results often come back in days; scans and biopsies can take longer, and the cause is not always clear at the first visit.
- A usually not painful lump that does not settle in a few weeks should be checked by a doctor without delay.
A plain-English summary. The detail — including risks and recovery — is below.

If the plan was to watch and wait, you are usually re-examined to see whether the swelling has settled.
What is a swollen glands and spleen assessment?
Lymph nodes are small glands, found in places like the neck, armpits and groin, that are part of the body's immune system. The spleen is an organ on the left side of the tummy that also helps fight infection and filter blood. Both can become enlarged for many reasons.
This assessment is the process a doctor uses to work out why a gland or the spleen is swollen. It usually starts with questions about your symptoms and an examination, then blood tests, and sometimes a scan or a sample (biopsy) of a gland.
Most swollen glands are caused by ordinary infections and settle on their own. But persistent, usually not painful or widespread swelling, or an enlarged spleen, can sometimes point to a blood condition such as lymphoma or leukaemia, so it is sensible to have it checked rather than ignored.
The assessment is about finding the cause. It is not a treatment, and a single appointment may not give a final answer until test results are back.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
History and examination
The specialist asks about how long the swelling has been there, pain, fevers, night sweats, weight loss, itching, infections and travel, then feels the glands in several...
Blood tests
A full blood count and other tests (such as kidney and liver function, inflammation markers, LDH, and sometimes tests for infections like glandular fever) help point towards...
Imaging
An ultrasound, CT or sometimes other scans can measure glands and the spleen, look at deeper areas that cannot be felt, and help decide whether a biopsy is needed.
Lymph node biopsy
Taking a sample of a gland — either with a needle or by removing the whole node — so it can be examined under a microscope. This is often the test that gives a firm diagnosis.
Preparing for your test
- Note when you first noticed the swelling, whether it has changed, and whether it is painful.
- Write down any fevers, drenching night sweats, unexplained weight loss, itching or unusual tiredness.
- List recent infections, illnesses, vaccinations and any travel abroad.
- Bring a list of your medicines, supplements and any known medical conditions.
- Mention any family history of blood conditions or cancer.
- If you have had previous blood tests or scans, bring the results or details.
- Wear clothing that makes it easy to examine your neck, armpits and tummy.
What happens
At the first appointment the specialist (often a haematologist) asks detailed questions and examines the glands in your neck, armpits and groin, and feels your tummy to check whether the liver or spleen is enlarged.
They will usually arrange blood tests on the same day. Depending on what they find, they may request a scan (such as an ultrasound or CT) and, if needed, arrange a biopsy of a gland.
You will be told what the likely causes are, which tests are being done and why, and when to expect results. Sometimes the plan is simply to re-examine you after a few weeks to see whether the swelling settles, which can be the safest and most informative next step.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- A private first appointment is not the right route if you are acutely unwell with high fever, severe pain or breathlessness — that needs urgent or emergency care.
- Assessment alone will not treat the underlying cause; it identifies it so the right treatment can be arranged.
- If a confirmed blood cancer is likely, ongoing care usually belongs within a specialist multidisciplinary team rather than a single private clinic.
- It is not a substitute for an urgent NHS referral when red-flag symptoms are present.
Delay or rearrange if…
- You have signs of serious infection (high fever, feeling very unwell) — these need treating first.
- You are pregnant or might be, as this affects which scans and tests are appropriate.
- Key earlier results or imaging are missing and would change what is done next.
- Symptoms are escalating quickly — in that case care should be brought forward, not delayed.
Alternatives to discuss
- Watchful waiting with a planned review, if the swelling is likely from a recent infection.
- Assessment through your GP and the NHS urgent-referral pathway.
- Treating an obvious infection first and re-checking the glands afterwards.
- A second opinion within the NHS if you are unsure about a plan.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Comfort, sedation or contrast choices
If local anaesthetic, sedation, contrast or pain relief is used, ask what is planned, why, and what it means afterwards.
Benefits
- Helps find a clear reason for the swelling rather than leaving it unexplained.
- Can provide early reassurance when the cause is a common infection or harmless.
- Picks up blood conditions such as lymphoma or leukaemia sooner, when this matters.
- Guides whether a biopsy or further tests are actually needed, avoiding unnecessary ones.
- Gives you a plan and a timeline, with a named team to contact about results.
Risks & complications
- Anxiety while waiting for results.
- Bruising or soreness from blood tests.
- Needing to come back for repeat checks or further tests before a cause is clear.
- Results that are inconclusive at first and need follow-up.
- Incidental findings on scans that need further tests but may turn out to be harmless.
- A biopsy that does not give enough tissue and needs repeating.
- Discomfort, small bleeding or bruising at a biopsy site.
- Infection or bleeding after a biopsy that needs treatment.
- Reaction to scan contrast dye, where it is used.
The main uncertainty is that the cause is not always obvious quickly, and a normal first set of tests does not always rule everything out. Ask your specialist what the likely causes are, which test would change the plan, and what should happen if the swelling does not settle or gets worse while you wait.
Published figures to discuss
This is an assessment rather than a treatment, so meaningful complication percentages are limited. The most important uncertainties are diagnostic: tests can be inconclusive, normal results do not always rule out every condition, and scans can show incidental findings that need further checking. Rates of complications from blood tests and biopsies are low but not zero.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from the assessment itself. The main thing afterwards is waiting for test results and following the agreed plan.
- Feeling worried while you wait for results — this is very common.
- Mild bruising at blood-test or biopsy sites.
- Being asked to come back for repeat examination or further tests.
- Glands that gradually settle on their own if the cause was an infection.
- Not having a firm answer at the very first appointment.
Aftercare
- Follow the agreed plan and attend any tests or follow-up appointments.
- Keep a note of any new symptoms, especially fevers, night sweats or weight loss, to report.
- Look after a biopsy site as advised and watch for redness, swelling or discharge.
- Ask how and when you will get your results, and who to contact if you do not hear.
- Do not assume a normal blood test rules everything out — keep follow-up appointments.
- Tell your team if the swelling grows quickly, becomes hard, or new lumps appear.
- Note of when the swelling started and how it has changed
- List of symptoms (fevers, sweats, weight loss, itching, tiredness)
- List of current medicines and supplements
- Details of recent infections, vaccinations or travel
- Any previous blood test or scan results
- Questions written down for the specialist
- Contact number for results and queries saved

General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A good outcome from the assessment is a clear explanation for the swelling and a plan you understand. Often this is reassuring — for example, a recent infection — and the glands settle.
Where a blood condition is found, finding it through proper assessment means it can be discussed by the right team and managed appropriately. A normal set of results is reassuring but does not always rule out every condition for ever, which is why follow-up and reporting new symptoms matter.
If the cause was an infection and the glands settle, no further checks are usually needed. If results are normal but the swelling persists, your specialist may re-examine you over time, because a picture can change and repeat assessment is sometimes the safest approach.
Related tests, treatments or support
Blood tests, imaging and biopsy are often done together as part of one assessment, building up a picture step by step. If a blood condition is confirmed, further staging tests may follow to understand its extent.
Follow-up & long-term care
Follow-up depends on what is found. It may be a single reassuring conversation about results, a repeat examination after a few weeks, or referral into a specialist blood-cancer pathway with its own team. Your team should tell you clearly how results will reach you and who to contact in the meantime.
Repeat, follow-on and what comes next
- Repeat blood tests or a repeat examination after a few weeks is common and often the safest next step.
- A biopsy sometimes needs repeating if the first sample does not give a clear answer.
- A normal first assessment may still be followed by further tests if symptoms persist or change.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear plan with named tests, timescales and a way to get your results.
- A named contact to call if you do not hear about results or develop new symptoms.
- An explicit safety net: what to watch for and what to do if the swelling worsens.
- Smooth coordination with the NHS and a specialist team if a serious condition is confirmed.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Length and number of specialist appointments.
- Which blood tests are needed and how specialised they are.
- Type of imaging (ultrasound, CT or other scans) and reporting by a specialist.
- Whether a biopsy is needed, and how it is taken and analysed.
- Whether a bone marrow test or further staging tests are required.
- Follow-up appointments and any onward referral or coordination of care.
- The specialist consultation fee, and the cost of any follow-up appointments.
- Which blood tests are included and which are charged separately.
- Imaging and the radiologist's reporting fee.
- Biopsy procedure and laboratory analysis fees, if a biopsy is needed.
- What happens, and what it costs, if results are inconclusive and more tests are needed.
- How care is coordinated with the NHS if a serious condition is found.
On the NHS? Assessment of swollen glands and an enlarged spleen is widely available on the NHS. If cancer needs ruling out, you may be referred on an urgent suspected-cancer pathway; its name and target differ across the UK (in England, the Faster Diagnosis Standard aims for cancer to be confirmed or ruled out within 28 days of referral). Private care may be used for speed of first appointment or a second opinion.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Being given a biopsy or scan without a clear explanation of what it will and will not show.
- False reassurance from a single normal blood test, without a plan for follow-up.
- Not being told who will see the results and how a serious diagnosis would be handled.
- Not understanding that the assessment finds a cause but does not treat it.
Marketing red flags
- Claims that a single scan or blood panel can definitely rule out all blood cancers.
- Pressure to pay for extensive tests before a basic history and examination.
- Promises of an instant diagnosis without proper laboratory analysis.
- Discouraging you from using NHS pathways when urgent referral is appropriate.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- What do you think is the most likely cause of my swelling?
- Which tests are you arranging, and what will each result change?
- Do I need a biopsy, and if so, what kind and why?
- What should happen if the swelling does not settle or gets worse?
- How and when will I get my results, and who do I contact in the meantime?
- If this turns out to be serious, who will look after me and how does that work with the NHS?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
