The general term non-Hodgkin's lymphomas covers several dozen different diseases of the lymphatic system. Some develop aggressively, while others take years.
At "K+31," we provide comprehensive diagnostics and treatment for lymphomas. Below, we explain the differences between diffuse and follicular forms, how lymphoma diagnosis is structured, and what modern treatment for non-Hodgkin's lymphoma includes.
This is a large group of tumors that arise from lymphatic tissue cells, most often from lymphocytes. Unlike Hodgkin's lymphoma, there is no single prognosis: each non-Hodgkin's lymphoma has its own characteristics of progression and prognosis.
The main characteristic is diversity. The tumor can grow:
It can even appear in organs outside the lymphatic system, which changes both the symptoms and the treatment approach.
The key difference lies in the tumor structure and cell composition. In Hodgkin's disease, specific Reed-Sternberg cells are found, while in other lymphomas the picture is different, so treatment regimens differ.
The group encompasses a variety of variations, but two forms are most commonly encountered at reception. These are conveniently thought of as two poles—fast and slow.
The most common aggressive variant, which develops from B-lymphocytes, diffuse large B-cell lymphoma grows rapidly and requires prompt treatment, but it responds well to treatment.
Opposite in its course. Follicular lymphoma is an indolent, or slow-growing, form; it can cause little or no symptoms for years and remains under control for a long time.
In addition to the two main forms, there are also rarer ones. These include:
The exact subtype is determined by tissue examination, and it determines the choice of therapy.
To make the differences between the two main forms clearer, we summarize them in a table.
| Parameter | Diffuse large B-cell | Follicular |
|---|---|---|
| Progression type | Aggressive | Indolent, slow |
| Progression | Rapid | Gradual, over years |
| Frequency | Most Frequently aggressive | Frequently indolent |
| Symptoms | Rapid node growth, intoxication | Long-term, asymptomatic node enlargement |
| Treatment | Immunochemotherapy | From observation to immunotherapy |
| Observation | Active treatment immediately | Sometimes watchful waiting |
How Apparently, the two forms require different reaction speeds and different amounts of assistance.
Manifestations depend on the type of tumor and its location. Some complaints are related to the nodes, while others reflect the body's overall response.
The most common symptom is painless swelling of the lymph nodes in the neck, armpits, or groin. The nodes may remain the only manifestation of the disease for a long time.
Along with the nodules, systemic complaints often appear. The main symptoms of lymphoma include:
These signs alone are nonspecific, but their combination is a compelling reason for examination.
When the tumor affects organs, other symptoms are added. Abdominal pain, bowel disturbances, and heaviness in the hypochondrium with an enlarged spleen or liver are possible.
There are situations that require immediate consultation. Persistent enlargement of lymph nodes, weight loss, persistent fever, and night sweats are all signs that a lymphoma oncologist should begin an examination as soon as possible. The sooner the diagnosis is confirmed or ruled out, the more confident the patient's decision will be.
A diagnosis is made based on tissue examination, not just laboratory tests. At our center, lymphoma diagnosis is performed in stages:
This procedure allows us not only to confirm the disease but also to accurately identify its variant.
The first appointment is a discussion and examination. The doctor evaluates the nodes and the patient's general condition, then determines which tests are needed first.
Blood tests reflect the activity of the process and organ function. They do not replace morphology, but they help assess anemia, inflammation, and the condition of the liver and kidneys.
The basis of diagnosis is an examination of the tissue of the affected node. A lymph node biopsy with histological examination reveals the tumor's structure and differentiates lymphoma from other diseases.
To determine the exact subtype, the tissue is further examined. Immunohistochemical examination identifies specific proteins on the cell surface and allows for the classification of the tumor to a specific variant.
The extent of the process is assessed using imaging techniques. CT and PET-CT show all lesions and their metabolic activity, and these same studies are then used to monitor treatment.
"In our practice, timely biopsy and immunohistochemical examination allow us to quickly establish an accurate diagnosis and select an effective treatment strategy." Therefore, we pay special attention to high-quality diagnostics and discussing each case at a consultation,"
— oncologist.
The disease is divided into four stages based on the number and location of lesions. Early stages are limited to a single area, while later stages involve organs and bone marrow. The extent of therapy depends on the stage of the lymphoma.
We've compiled the most frequently asked questions from patients. The answers are general and do not replace an in-person consultation.

Causes and risk factors
The exact cause is often impossible to determine. It involves the accumulation of random changes in cells, rather than infection in the common sense.
Genetic and immunological factors
Some cases are associated with defects in lymphocyte genes and immune dysfunction. Congenital and acquired immunodeficiencies increase the likelihood of tumor development.
The impact of chronic infections
Long-term infections play a significant role. The development of some lymphomas is associated with the Epstein-Barr virus, hepatitis, and the Helicobacter pylori bacterium in gastric MALT lymphoma.
Other risk factors
External influences and age complete the list. Exposure to certain chemicals, ionizing radiation, and a decline in the immune response over time are all significant; Let's list the most significant circumstances:
None of these factors makes the disease inevitable, but they increase the risk and require attention to health.
