Pulmonary aggressive lymphoma refers to aggressive lymphoma that occurs in the lungs. The pathological types of aggressive lymphoma include primitive B lymphocyte lymphoma, primitive immune cell lymphoma, diffuse large B-cell lymphoma, primitive T-lymphocyte lymphoma, and mesenchymal large B-cell lymphoma. Non-Hodgkin’s lymphoma is divided into aggressive lymphoma and inert lymphoma. Aggressive lymphoma has a higher degree of malignancy than inert lymphoma, the disease develops rapidly, the patient’s condition is more severe, and its prognosis is generally worse than that of inert lymphoma. Therefore, patients with aggressive lymphoma usually need to undergo chemotherapy, radiotherapy and other comprehensive treatments. Patients with pulmonary aggressive lymphoma need to go to the hospital in time, complete the examination, clarify the pathological type of lymphoma, and then choose the appropriate treatment plan under the guidance of the doctor to avoid further progression of the disease.
