Lymphoma

Lymphocytes normally help fight infection. In lymphoma they grow in lymph nodes, the spleen, bone marrow, or other organs without proper control. Hodgkin lymphoma is recognised by a particular cell on the biopsy and is often highly treatable. Non-Hodgkin lymphoma is a large group. Diffuse large B-cell lymphoma is a common fast-growing type. Follicular lymphoma is a common slower type. T-cell lymphomas are less common and need their own plan. The subtype is the whole conversation. Treatment should not start from a scan that only says nodes are enlarged.

Lymphoma is not the same as leukemia. Both are blood cancers, but they start and are classified differently. Some illnesses sit near that boundary and need a haematopathologist’s report. Leukemia has its own page because the treatments and the urgency differ. A high white cell count, by itself, is not either diagnosis.

Painless enlargement of nodes in the neck, armpit, or groin is the classic sign. Nodes from infection are far more common, especially in younger people, and they often shrink over a few weeks. Nodes that keep growing, feel hard, or come with fever, drenching night sweats, or marked weight loss need examination. Itch, cough, or abdominal fullness can occur. These symptoms are also caused by tuberculosis, other infections, and autoimmune disease, which matter in India and must not be missed by jumping to cancer treatment.

There is no useful screening test for lymphoma in people who feel well. The route to diagnosis is a proper assessment of a persistent node or an unexplained symptom. Antibiotics are reasonable when infection is likely. They are not a substitute for biopsy when a node is still growing after the infection has been treated.

An adequate biopsy, often removal of a whole node, is the key test. A fine-needle sample is sometimes not enough to name the subtype. The tissue is examined with a microscope and with markers that identify the cell of origin. That report should be read by a pathologist used to lymphomas. If the first sample is inconclusive, a second biopsy is safer than guessing a treatment. Steroids given before the biopsy can blur the result, so they should not be started casually for a suspicious node.

Once the subtype is known, staging looks at where the disease is. PET-CT is standard for many lymphomas. CT is used in others. Blood tests look at counts, kidney and liver function, lactate dehydrogenase, and infections such as hepatitis B, hepatitis C, and HIV, because those results change the safety of treatment. A bone marrow test is added when it would change the stage or the plan. Heart tests are done before some chemotherapy drugs. Not every person needs every test on day one, but missing hepatitis status before antibody therapy can be dangerous.

Fast-growing B-cell lymphomas are usually treated with combination chemotherapy plus an antibody, given in cycles. The goal in many of these illnesses is cure. Some early, favourable Hodgkin lymphomas are treated with less chemotherapy and with radiation to a small area. Radiation is planned by a radiation oncologist. The number of cycles depends on stage and on how the PET scan looks part-way through treatment. A good early response can safely shorten therapy in defined situations. A poor response changes the plan. Those rules are specific. They are not a reason to stop treatment because you feel better.

Slow-growing lymphomas, such as many follicular lymphomas, may not need treatment at diagnosis. Watching with clinic visits is an accepted approach when there are no troublesome symptoms, no threat to an organ, and no low blood counts from the disease. Treatment starts when those conditions change. It may include antibody therapy, chemotherapy, or both. Immunotherapy and targeted drugs are used in relapse for selected subtypes. A stem cell transplant is considered for some relapsed lymphomas and needs a dedicated transplant discussion. It is not the first step for most people.

Side effects include low white cells, hair loss with some regimens, nausea, and fatigue. One drug used in several regimens can affect the heart, which is why heart function is checked. Nerve tingling can occur. Fever during chemotherapy is an emergency because counts may be low. Tumour lysis, a rapid breakdown of cancer cells, is a risk when treatment starts for a bulky fast-growing lymphoma and is prevented with fluids and medicines in hospital when needed. Report breathlessness, chest pain, or a new neurological symptom rather than waiting.

Infection precautions matter most when white cells are low: fever is a same-day problem, and some live vaccines are avoided around treatment. Hepatitis, if present, may need antiviral cover. Fertility should be discussed before chemotherapy if a future pregnancy matters, because referral takes time. Work and study can often continue with adjustments around infusion weeks. That depends on the regimen and the job. It should be planned, not assumed.

After treatment aimed at cure, follow-up looks for relapse and for late effects, including thyroid, heart, and second cancers in people who had particular drugs or radiation. Routine PET scans forever are not helpful in someone who is well. New lumps, sweats, or weight loss should be reported. A slow-growing lymphoma that was watched remains on a clinic schedule even when no drug has been started. Feeling well is the aim of that strategy. It is not a reason to disappear from follow-up.

Bring the full biopsy report, not only the line that says lymphoma, plus any PET or CT and the hepatitis and HIV tests if they were done. List steroids, herbal medicines, and antibiotics you have already taken, because steroids before a proper biopsy can blur the diagnosis. Note fever, sweats, weight change, and whether nodes are still growing. If a previous doctor called the illness tuberculosis or an infection, bring that treatment history too.

Ask the subtype in words you can repeat, whether treatment starts now or whether watching is safe, and what the goal is: cure, long control, or symptom relief. Ask how many cycles are planned and what a midway PET scan would change. Ask about fertility, heart checks, and the number to call for fever. Slow-growing and fast-growing lymphomas should not be managed with the same urgency. The report is what tells them apart, and the visit is where that difference should be explained.

A visit about lymphoma is used to read the records you already have, explain them in plain language, and outline options that may apply. Bring the biopsy or pathology report, scan CDs or reports, blood tests, and a list of treatment already given, including dates and drug names if you have them. A family member can come with you. The visit is not an emergency assessment, and it does not confirm a plan until the records have been reviewed.

Dr. Nishith Vaddeboina is a medical oncologist. Appointments published on this website are at American Oncology Institute, Nallagandla, Hyderabad. The biography also lists consultant work at Renova Century Hospitals. Confirm the hospital when you book. Plans are discussed against recognised guidance, including NCCN, ESMO, and ASCO, and then adjusted to the person in the room. Nothing on this page replaces that conversation.

A node that keeps enlarging, or fever, drenching sweats, and weight loss together, should be examined. During chemotherapy, fever, bleeding, chest pain, or severe breathlessness need urgent care. A single small node with a recent throat infection is often observed. This page cannot tell those situations apart for you.
