A cough or breathlessness that will not settle almost always has an ordinary cause. But when it comes with painless chest node swelling, it is worth ruling out a mediastinal lymphoma. This guide explains the symptoms, the common causes to check first, and when a biopsy is needed.
A cough or breathlessness that lingers is one of the most common reasons people see a doctor, and the overwhelming majority of cases come from ordinary, treatable causes: a lingering chest infection, asthma, acid reflux, smoking, or post-viral airway irritation. In Telangana and Andhra Pradesh, tuberculosis (TB) is a genuinely common cause of a weeks-long cough and of enlarged chest lymph nodes, and it must always be considered early. So if you have a persistent cough, the first job is to check for these — not to assume the worst.
Occasionally, though, a cough or breathlessness comes from lymphoma sitting in the mediastinum — the central compartment of the chest, between the lungs, where many lymph nodes live. When these nodes enlarge, they can press on the windpipe, the large airways or the lung, producing a dry persistent cough lymphoma patients often describe, breathlessness or chest pressure. This page explains the mediastinal lymphoma symptoms, how they differ from the common causes, and — importantly — the specific red flags that mean a chest node swelling needs a biopsy rather than another course of antibiotics.
Lymphoma is very treatable when found. For the full picture, see our Lymphoma hub and our Lymphoma Treatment in Hyderabad page.
India accounts for roughly a quarter of the world's tuberculosis cases, and TB is one of the most common causes of enlarged chest and neck lymph nodes in our region. Because TB and lymphoma can look almost identical on a CT scan — both can produce a mediastinal mass and B-type symptoms — a tissue biopsy is the only reliable way to tell them apart. This is exactly why a chest node or mass that does not settle should be biopsied rather than treated blindly. (Source: WHO Global TB Report; NCCN & ESMO lymphoma guidelines on tissue diagnosis.)
When lymphoma forms a mass of enlarged nodes in the centre of the chest, the symptoms come from that mass pressing on nearby structures. These signs overlap with common lung conditions — which is why the pattern matters more than any single symptom.
A cough that does not settle with usual treatment and is not productive of much phlegm. A chest mass can irritate the airways. This is different from an infective cough, which usually improves within one to two weeks.
Feeling short of breath — often noticed on exertion first, then when lying flat. It reflects pressure on the airways or lung from an enlarging mediastinal mass rather than a problem with the lung itself.
A dull ache or tightness in the chest, a change in the voice, or trouble swallowing can occur when the mass presses on the windpipe, the nerve to the voice box or the food pipe.
If the mass presses on the large vein returning blood from the head — the superior vena cava — it can cause swelling of the face, neck and arms, headache and prominent neck veins. This SVC obstruction needs urgent medical review.
Unexplained fever, drenching night sweats and unexplained weight loss. When these accompany a chest problem, doctors take it more seriously.
Sometimes a mediastinal lymphoma comes with a painless lump above the collarbone or in the neck. A painless node that persists is easier to biopsy and often the key to the diagnosis.
Having one of these symptoms does not mean you have lymphoma — most people with a cough do not. It is the combination, and above all a symptom that is persistent and progressive, that prompts investigation.

If a persistent cough or breathlessness has lasted beyond three to four weeks — or comes with chest node swelling or B symptoms — CION's team can arrange the right scans, biopsy and review, quickly.
Most coughs settle. The features that should make you and your doctor look harder — and consider a scan and a biopsy rather than another empirical course of treatment — are specific and worth knowing:
The single most important message: a chest node or mass that does not settle should be biopsied. TB and lymphoma can look identical on imaging, and treating one when it is really the other loses valuable time. This applies whether your symptom is a cough, a lump, or an unexplained fever — see how it fits the wider picture on our 'Do I have lymphoma?' guide and our page on whether a node is TB or lymphoma.
Reaching a confident diagnosis — and telling lymphoma apart from TB, sarcoidosis or a lung condition — follows a clear pathway. CION delivers the imaging, biopsy coordination, pathology and treatment planning directly.
A chest X-ray often first reveals a widened mediastinum. A CT scan then defines the size and position of the chest node swelling and its relationship to the airways and great vessels. A PET-CT is frequently added to map how widely the disease is spread and to guide where best to biopsy.
Imaging can strongly suggest lymphoma, but only a tissue biopsy confirms it and identifies the exact type. A sample of the mass or an accessible node is examined by a pathologist and tested with immunohistochemistry — markers such as CD20, CD30 and cell-of-origin — to distinguish, for example, classical Hodgkin lymphoma from primary mediastinal B-cell lymphoma, and both from TB. Biopsy is coordinated directly by the CION team.
Blood tests and, in selected cases, a bone-marrow examination complete the staging. Every case is then reviewed by CION's multidisciplinary tumour board before a plan is set, so the treatment fits the exact type and stage.
The encouraging news is that mediastinal lymphomas are among the more treatable cancers, and many are potentially curable. The exact plan depends on the type and stage confirmed on biopsy, and every case is reviewed by CION's tumour board first.
Treatment typically centres on chemotherapy, delivered directly at CION. Depending on the type, an anti-CD20 monoclonal antibody may be added, and precision radiation therapy (IMRT) is sometimes used for a bulky chest mass. Specific drug combinations are chosen case by case — you can read how these decisions are made on our Lymphoma Treatment in Hyderabad page. If a stem-cell transplant is ever required, it is coordinated through accredited partner facilities, while chemotherapy, antibody therapy, radiation, biopsy and follow-up care are provided directly.
Outcomes vary a great deal by type, stage and general health, but they are often good. In published series, Hodgkin lymphoma — a common cause of a chest mass in young adults — has around 80–90% long-term survival, and diffuse large B-cell lymphoma around 60–70% (per NCCN and ESMO data). These are population figures, not a prediction for any one person — outcomes vary by individual. The strongest driver of a good outcome is an accurate, early diagnosis and a plan tailored to the exact type.

When lymphoma involves lymph nodes in the centre of the chest — the mediastinum — the enlarged nodes can press on the windpipe, the large airways or the lung, producing a dry, persistent cough lymphoma patients often describe, breathlessness, or a feeling of chest pressure. That said, most persistent coughs come from ordinary causes — chest infections, asthma, acid reflux, smoking or, in Telangana and Andhra Pradesh, tuberculosis. A cough is only a red flag for lymphoma when it lasts beyond three to four weeks, does not settle with usual treatment, or comes with painless node swelling or B symptoms (fever, drenching night sweats, unexplained weight loss). See our Lymphoma Treatment in Hyderabad page for how this is worked up.
The classic mediastinal lymphoma symptoms come from a mass of enlarged nodes in the front and centre of the chest. They can include a dry cough that does not go away, breathlessness (especially when lying flat), chest tightness or a dull ache, a hoarse voice, and difficulty swallowing. If the mass presses on the large vein returning blood from the head — the superior vena cava — it can cause swelling of the face, neck or arms, headache and visible neck veins; this is called SVC obstruction and needs urgent review. Some people also have B symptoms — fever, drenching night sweats and unexplained weight loss. Many of these signs overlap with common lung conditions, so imaging and, ultimately, a biopsy are what settle the diagnosis.
They can look similar at first, which is exactly why careful assessment matters. A chest infection usually brings fever, coloured phlegm and a cough that improves within one to two weeks of treatment. Tuberculosis — genuinely common in Telangana and Andhra Pradesh — tends to cause a cough lasting weeks, evening fevers, night sweats and weight loss, and can also enlarge chest nodes. Mediastinal lymphoma typically causes a dry, persistent cough or breathlessness with painless chest node swelling that does not respond to antibiotics or anti-TB treatment. Because TB and lymphoma can mimic each other on a scan, a tissue biopsy is the only reliable way to tell them apart. Never assume — a node or mass that does not settle needs a biopsy rather than another empirical course of treatment.
As a rule of thumb, a cough that persists beyond three to four weeks despite treatment deserves proper investigation — starting with a chest X-ray or CT. You should seek review sooner if the cough comes with breathlessness at rest, coughing up blood, swelling of the face or neck, a painless lump above the collarbone, or B symptoms (fever, drenching night sweats, unexplained weight loss). These do not mean you have lymphoma — most people with a long cough do not — but they are the features that make doctors look harder. If you are worried, book a free consultation with the CION team rather than waiting to see if it clears.
"Mediastinal lymphoma" simply describes lymphoma located in the mediastinum — the central chest. Several types can present this way. The two most common are classical Hodgkin lymphoma, which often forms a mass in the front of the chest in young adults, and primary mediastinal B-cell lymphoma (PMBCL) — an aggressive non-Hodgkin type that typically affects women in their 20s to 40s and grows quickly as a bulky chest mass. Distinguishing them, and from other node causes, needs a biopsy with specialised pathology and molecular testing. The type then guides treatment, which is why an accurate diagnosis comes first. Read more on our dedicated PMBCL page.
Diagnosis begins with imaging — usually a chest X-ray followed by a CT scan — to define the size and position of the chest node swelling. A PET-CT is often added to map how widely the disease is spread. The diagnosis itself, however, can only be confirmed on a tissue biopsy: a sample of the mass is examined by a pathologist and tested for markers such as CD20, CD30 and cell-of-origin, which identify the exact lymphoma type. CION delivers biopsy coordination, pathology, imaging and treatment planning directly, with every case reviewed by a multidisciplinary tumour board. Blood tests and, in some cases, a bone-marrow examination complete the picture. See the full pathway on our Lymphoma Treatment in Hyderabad page.
