Hematolymphoma is a malignant tumor originating from the blood-lymphatic system. Since the blood-lymphatic system is spread all over the body, lymphoma can occur in many parts of the body. The main clinical manifestation of hematologic lymphoma is painless, progressive lymph node enlargement, which may be accompanied by systemic symptoms such as fever, night sweats, and weight loss. Hematologic lymphoma can be divided into Hodgkin’s lymphoma and non-Hodgkin’s lymphoma according to the type of pathology. Hodgkin’s lymphoma is mainly seen in Europe, America and other developed countries, and non-Hodgkin’s lymphoma is dominant in China. Non-Hodgkin’s lymphoma contains dozens or hundreds of subtypes, including inert and slow-developing lymphomas, such as follicular lymphoma, and fast-developing ones, such as diffuse large B-cell lymphoma and Burkitt’s lymphoma. Treatment for lymphoma is based on chemotherapy or radiation therapy, and different types of lymphoma have different outcomes and different prognoses.
