Lymph nodes are collectively important immune organs. Various types of pathogenic microbial infections, chemical drugs, foreign poisons, foreign bodies, the body’s own metabolites and other factors can cause proliferation of cellular components in lymph nodes, such as lymphocytes, resulting in enlargement of lymph nodes. The proliferation of lymph nodes can be made reactive or tumorigenic. Neoplastic hyperplasia will lead to lymphatic tissue tumors, one of which is a malignant tumor called malignant lymphoma, or lymphoma. Lymphoma is the result of neoplastic proliferation of lymphocytes and their precursor cells in the lymph nodes and outside the nodes. It is a malignant tumor of the immune system that occurs in lymphoid tissue and is one of the first malignant tumors of the hematological system to be discovered. Lymphoma can be divided into two categories: Hodgkin’s lymphoma (HL) and non-Hodgkin’s lymphoma (NHL). Can lymphoma be cured? There are various factors that determine the treatment effect of lymphoma. Whether early detection, early diagnosis and persistent treatment are the key factors to determine the effectiveness of treatment. With the development of medical science and technology and intensive research, the treatment of lymphoma has made great progress, and lymphoma has become one of the tumors that can be cured by chemotherapy. Even if it is not cured, many lymphoma patients can survive for a long time through effective treatment. Therefore, lymphoma patients must have the confidence and determination to overcome the disease and actively cooperate with the doctor’s treatment. How to treat lymphoma? The treatment of lymphoma is mostly based on comprehensive treatment, and chemotherapy is one of the main treatment means for lymphoma. Combination of chemotherapy and radiotherapy with chemotherapy as the main treatment, the treatment strategies for Hodgkin’s lymphoma and non-Hodgkin’s lymphoma are not exactly the same. Non-Hodgkin’s lymphoma also determines the treatment strategy for non-Hodgkin’s lymphoma to be chemotherapy-based because more focal centers occur and the therapeutic effect of radiotherapy mammals Hodgkin’s lymphoma. In addition to combination therapy, the treatment options for lymphoma are biological therapy, bone marrow or hematopoietic stem cell transplantation and surgical treatment.
