The survival time of lymphoma patients is not determinable and is related to the type and stage of the tumor as well as the patient’s individual physical condition and treatment. Lymphoma, professionally known as lymphoma, includes many types and varies greatly in malignancy and treatment effects. Lymphoma mostly manifests as painless lymph node enlargement and liver and spleen enlargement. Early stage Hodgkin’s lymphoma has a better prognosis, and many patients can be cured and survive for a long time. Most inert non-Hodgkin lymphomas are less malignant, develop slowly, and have a longer survival period. However, aggressive lymphomas such as diffuse large B-cell lymphoma and lymphoblastoid lymphoma and T-cell lymphoma are fast progressing, highly malignant and poorly treated, and the survival time is related to the patient’s physical condition and stage, ranging from six months to several years. If painless lymph node enlargement occurs, it is recommended to visit the hematology or oncology department in time to clarify the diagnosis and take targeted treatment according to the type and stage of the disease. Patients need to pay attention to rest, eat a light diet and cooperate with doctors for active treatment.
