From the medical point of view, there is no difference between lymphoma and lymphoma, one of them is a terminology and the other is a common name. Lymphoma is malignant in medical terminology, and there is no such thing as benign or malignant lymphoma, it is just a name. If you want to make a clear distinction, there is a difference between tumor and cancer in medicine, but there is no difference between lymphoma and lymphoma in the common name and medical terminology in ordinary life, and the two can be equated. Usually the difference between tumor and cancer is as follows: 1. Tumor: it refers to the lumpy changes arising from the body surface or tissues, which can be divided into benign and malignant in pathological classification, for example, osteosarcoma is malignant although it is called tumor. 2. Carcinoma: a malignant tumor originating from epithelial tissue, with a narrower definition. Patients suffering from lymphoma or cancer are advised to go to the hospital for timely consultation and treatment.
