The survival period of malignant lymphoma is related to the pathological type and stage of the disease, as follows: 1. 5-year survival rate after surgery can reach about 80%, and 10-year survival rate after surgery can also reach 60%-70%; 2. 5-7 years for patients with low malignancy; 3. 3-4 years for patients with moderate malignancy; 4. 1 year for patients with high malignancy. In the same type, the earlier the disease stage, the better the prognosis, while the elderly and children have a relatively poor prognosis. Therefore, after discovering the disease, it is important to go to the hospital as early as possible for evaluation, determine the treatment plan and treat as early as possible. Patients also need to maintain a good state of mind, strengthen nutrition, and exercise appropriately, which can help to improve survival.
