Hodgkin vs Non-Hodgkin Lymphoma — Key Differences Explained Simply

The main difference is a specific cell. Hodgkin lymphoma contains an abnormal cell called the Reed-Sternberg cell, which a pathologist can see under the microscope. Non-Hodgkin lymphoma does not have these classic cells. This single feature, found on biopsy, decides which family your lymphoma belongs to. The two families then differ in how common they are, the typical age affected, how they spread, and how they are treated. That is why a careful biopsy report matters so much. At CION, a senior haemato-oncologist confirms your exact type before any treatment plan begins, so your care is built on a correct diagnosis.

No. Reed-Sternberg cells are the hallmark of Hodgkin lymphoma. They are large, abnormal lymphocytes that look distinct under the microscope. When a pathologist sees these cells in a lymph node biopsy, the diagnosis is Hodgkin lymphoma. Non-Hodgkin lymphoma, by definition, does not contain classic Reed-Sternberg cells. This is exactly why a biopsy, not just a scan, is essential to tell the two apart. A scan can show a swollen node, but only looking at the tissue can identify these cells. If you are unsure what your report shows, our team will explain it to you in plain language.

Non-Hodgkin lymphoma is far more common. Roughly nine out of ten lymphomas are non-Hodgkin, while about one in ten is Hodgkin. Non-Hodgkin lymphoma is also a much larger group, with many different subtypes that behave differently from each other. Hodgkin lymphoma has fewer, more clearly defined subtypes. Being more common does not mean more dangerous. Many subtypes of non-Hodgkin lymphoma respond very well to treatment, and Hodgkin lymphoma is often highly treatable too. The right approach depends entirely on your specific subtype and stage, which is why an accurate diagnosis comes first in every plan we make.

Age is one helpful clue, but it never decides the diagnosis alone. Hodgkin lymphoma often appears in two age groups: young adults aged about 15 to 35, and adults over 55. Non-Hodgkin lymphoma can occur at any age, but the risk generally rises as people get older, especially after 60. These are broad patterns, not rules. A teenager can have non-Hodgkin lymphoma, and an older adult can have Hodgkin lymphoma. Only a biopsy can confirm the true type. We use age as part of the full picture, alongside your biopsy, scans and blood tests, to understand your situation accurately.

Hodgkin lymphoma usually spreads in an orderly way. It tends to move from one group of lymph nodes to the next nearby group, step by step. This predictable pattern can make it easier to stage. Non-Hodgkin lymphoma spreads less predictably. It may skip areas, appear in several places at once, or involve organs outside the lymph nodes. This is one reason staging matters so much for both types. We often use a PET-CT scan to map exactly where the lymphoma is before planning treatment. Understanding the spread helps your team choose therapy that targets every affected area without overtreating.

Both can have a good outlook, and it is honest to say it depends on the type and stage, not the family name alone. Hodgkin lymphoma is often highly treatable, especially when found early. Non-Hodgkin lymphoma covers many subtypes, so the outlook varies widely; some grow slowly and some grow fast, and many respond very well to modern treatment. We do not believe in false promises or guarantees. Instead, your oncologist will explain your realistic outlook based on your subtype, stage and overall health. A tumour board reviews every patient so your prognosis and plan reflect a team's judgement, not one opinion.

B symptoms are three specific signs that doctors look for in both Hodgkin and non-Hodgkin lymphoma. They are unexplained fever, drenching night sweats, and unexplained weight loss of more than ten percent of your body weight. These symptoms are important because they affect staging and help guide treatment. Their presence is recorded as a B after the stage number; their absence is recorded as an A. Having B symptoms does not mean your case is hopeless, but it tells your team how active the disease may be. If you notice these symptoms lasting more than two weeks, please get checked promptly so nothing is missed.

The most important test is a biopsy, where a doctor removes a piece of an affected lymph node or tissue. A pathologist examines it to confirm whether it is lymphoma and, crucially, whether Reed-Sternberg cells are present. This tells Hodgkin from non-Hodgkin lymphoma. After diagnosis, staging tests such as a PET-CT scan and blood tests show how far it has spread. At CION, we arrange only the tests that genuinely help your plan, never unnecessary ones, and we explain costs upfront. Your case is then reviewed by our tumour board before treatment. You deserve a diagnosis you can trust and understand fully.

Yes, many lymphomas respond well to treatment, and some are among the more treatable cancers. Treatment depends on the type, subtype and stage. It may include chemotherapy, immunotherapy, targeted therapy, radiation, or a combination. Some slow-growing non-Hodgkin lymphomas may even be watched carefully before treatment starts. We cannot promise a cure for anyone, and we never would, but we can promise a clear, honest plan made for healing, not billing. Every plan is reviewed by our tumour board. Your senior oncologist will explain each option, the likely benefits, the side effects, and the costs in a calm 45-minute consultation.

Lymphoma is complex, with many subtypes that look similar but behave differently. The exact subtype changes the treatment, so getting the diagnosis right is vital. A second opinion lets an experienced haemato-oncologist review your biopsy and scans to confirm the type and stage before treatment begins. This can prevent under-treatment or over-treatment. At CION, your second opinion is free and unhurried, and you are under no pressure to switch your care to us. With 17 super-specialist oncologists and a tumour board for every patient, our goal is simply to make sure you have the clearest, most accurate picture. You deserve confidence in your plan.
