How long lymphoma can live is mainly related to the nature of the tumor, treatment and the patient’s personal constitution, etc. It should be analyzed specifically and cannot be generalized. Lymphoma is a malignant tumor of the blood system, and the survival period of each patient varies greatly. If lymphoma is of low malignancy, early detection, good health and active treatment, the prognosis is usually good and the survival time is long, generally more than 10 years. Late detection results in a correspondingly shorter survival period. In the case of highly malignant lymphoma, where the patient is not actively treated or is treated less effectively, the survival period is shorter, usually 1-2 years. However, for patients with highly malignant lymphoma, the survival period can be extended accordingly after applying new targeted drugs for treatment or undergoing transplantation, but the specific time needs to vary from person to person. Patients with lymphoma are recommended to go to the medical oncology department of regular hospitals for timely examination, and professional doctors will formulate rationalized treatment plans according to individual patients’ conditions.
