Non-Hodgkin lymphoma

Non-Hodgkin malignant lymphomas are hematological malignancies that have in common their origin in lymphoid cells in different stages of development. The term covers more than 20 different types of cancer, each with its own individual characteristics. In NHL, a lymphoid cell is reproduced uncontrollably, causing the organ where it occurs to swell. They can occur in any part of the body and from there spread to other organs and tissues. For example, in a lymph node, the skin, spleen or other organs. They are more common among men and patients with diseases of the immune system (AIDS, immunodeficiency, organ transplant recipients and autoimmune diseases) and infections (gastritis due to Helicobacter, Epstein-Barr virus). Symptoms are variable and depend on each type of specific lymphoma. Most are detected as a result of an adenopathy (large or inflamed lymph node). There may be fever, night sweats, weight loss, fatigue and recurrent infections. Treatment will depend on the type of lymphoma, age, the patient's overall status and to what extent the tumor has spread. It may be chemotherapy and/or radiotherapy. The prognosis is very variable according to the type of tumor.
