Lymphoma

**Lymphoma** is a malignant tumor of lymphatic tissue that most often affects the lymph nodes and bone marrow. This type of cancer is less common than breast, stomach and lung cancer. Lymphomas may or may not be associated with the immune system. Some types of lymphoma are hereditary and are associated with changes in immune system genes. In severe cases, chemotherapy or radiation therapy is prescribed to suppress tumor growth.

Lymphadenopathy is a nonspecific diagnosis determined by the detection of enlarged lymph nodes and their metastasis. This group of tumor diseases belongs to the group of lymphoproliferative diseases of lymphoid tissue and is combined under a single term in most Western clinics.

The disease is characterized by a slow increase in symptoms and has no signs of direct infection of the lymph nodes. The only clinical manifestation is enlargement of lymph nodes or a group of lymph nodes. The disease is characterized by an increase in all groups of peripheral lymph nodes, which is often accompanied by the presence of systemic manifestations. Lymphadenopathy is divided into reactive, reactive-hyperplastic forms of infectious mononucleosis, which are outflow lymphadenopathy. Various other infections, sepsis, severe radiation injuries, immunodeficiency states and malignant diseases can cause damage to the lymphatic system. In such cases, lymphadenitis serves as a marker of the underlying disease, and pathognomic signs are changes in the cellular composition of peripheral blood, increased ESR, signs of anemia, and histological confirmation of morphological changes in the affected nodes. Mononucleosis is usually accompanied by an acute and cyclical increase in body temperature to 39°C and above, which lasts for 2-3 weeks. Enlarged lymph nodes, sometimes numerous, are painless or slightly painful. Such patients consult a doctor, as a rule, with significant general weakness and rapid fatigue, headache and loss of appetite.
