Lymphoma is a systemic disease. Lymphoma is a malignant tumor disease originating from the immune system. Since the lymphatic system is present throughout all parts of the body, lymphoma is a systemic disease and can develop in any part of the body where the lymphatic system is present. Clinically, lymphoma can be divided into two different types: Hodgkin’s lymphoma and non-Hodgkin’s lymphoma, in which the overall prognosis of non-Hodgkin’s lymphoma is relatively worse. Since the development and aggravation of lymphoma is likely to endanger the life of an individual, it is important for individuals to recognize the seriousness of lymphoma. Not only should they have regular medical checkups, but they should also pay attention to the changes in their bodies, and if they find some unexplained abnormal lumps under the skin, they should seek medical treatment in time.
