A lump in the neck, armpit or groin can raise immediate fears about cancer. Lymph nodes are part of the immune system, and infections are a common reason for enlargement. A swelling that persists or grows still deserves an examination. An online description cannot tell whether the lump is a lymph node or what is causing it. MedlinePlus: Swollen lymph nodes
Know when not to wait
Swelling with difficulty breathing or marked difficulty swallowing needs urgent medical help. If breathing difficulty is severe, such as gasping or being unable to speak normally, go to the nearest emergency department or call local emergency services. Do not wait for an NGO callback or a routine appointment. NHS: Swollen glands; NHS: Shortness of breath
Arrange a doctor’s assessment if a node is enlarging, has not started going down within about a week, feels hard or fixed, or is above or below the collarbone. Seek assessment sooner with night sweats, high fever or no obvious infection. These are reasons to investigate, not proof of cancer. NHS: Swollen glands
Describe the lump and the rest of your health
Before the visit, prepare a brief record. You do not need to repeatedly press the lump or decide whether its texture matches an internet photograph. Ask the clinician to examine it.
- Where is the swelling, and when did you first notice it?
- Has it become larger, smaller or stayed similar? Are there other lumps?
- Is it painful, red or associated with a recent throat, dental, ear or skin problem?
- Have you had fever, drenching night sweats, unexplained weight loss or a persistent cough?
- What medicines are you taking? Have you had a recent illness or vaccination?
- Have you already been examined or treated? Bring the prescription and any test results.
Lymph-node assessment considers the history, examination and associated symptoms. Medicines, infections and immune conditions can also be relevant. MedlinePlus: Swollen lymph nodes
Why the doctor may discuss infections as well as cancer
In India, tuberculosis may be among the conditions a clinician considers for persistent enlarged lymph nodes. The Government of India’s INDEX-TB guidance describes lymph-node TB and stresses that chronic lymph-node swelling has several possible diagnoses. Do not assume a lump is either TB or cancer before appropriate assessment. Central TB Division, MoHFW: INDEX-TB Guidelines, lymph node TB chapter
Painless swelling can occur in lymphoma, but the symptoms overlap with other conditions. A referral to a specialist means the problem needs investigation; it does not by itself confirm lymphoma. NHS: Symptoms of non-Hodgkin lymphoma
Understand what each proposed test is meant to answer
Depending on the findings, the doctor may discuss blood tests, imaging or a sample from the node. A biopsy examines cells or tissue. If lymphoma is suspected, sampling may involve a needle or removal of part or all of a node; the specialist chooses the approach for the clinical question. MedlinePlus: Swollen lymph nodes; NHS: Tests and next steps for non-Hodgkin lymphoma
Ask what information the proposed sample can provide, whether further sampling might be needed, and which clinician will explain the result. Before the procedure, request its preparation instructions, expected costs and aftercare contact. Do not stop a prescribed medicine unless the team tells you to.
If tissue is sent for analysis, keep the complete report. Our guide to reading a cancer biopsy report explains useful report headings and questions. Receiving a biopsy appointment is not the same as receiving a cancer diagnosis.
Make observation an active plan
If the clinician recommends watching the node for a period, ask for a review date rather than leaving with “wait and see”. Record who to contact if it grows or new symptoms appear. If treatment is prescribed for a suspected infection, ask when improvement should be reassessed and what happens if it does not occur.
- What is your working explanation for the swelling?
- What finding would make you recommend a scan, biopsy or specialist referral?
- When should I return even if nothing changes?
- Who is responsible for tracking pending results?
- Which changes should make me seek help before the planned review?
For families travelling between a district hospital, private laboratory and specialist centre, a simple dated list prevents the same result being overlooked or an unfinished test being mistaken for a completed investigation. Ask for a copy of the plan before leaving.
