Lymphoma or lymphatic cancer is a very serious and life threatening disease. In this country there is an estimated 63,900 new cases, 7,100 of which are Hodgkin's lymphoma as opposed to non-Hodgkin's lymphoma. Since around the 70's the occurrence of non-Hodgkin's lymphoma has almost doubled while the occurrence of Hodgkin's disease has declined. (Steen, 1993)
Lymphoma is the name given to a cancer that infects the lymphatic system. In a case of lymphoma the lymphatic system has cells that multiply and cannot be stopped. There are two main types of lymphoma, Hodgkin's and non-Hodgkin's. Non-Hodgkin's lymphoma is called lymphoma and Hodgkin's type lymphoma is called Hodgkin's disease. Hodgkin's disease is different from non-Hodgkin's disease in that Hodgkin's disease has a Reed-Sternberg cell present in the areas infected with the cancer. Hodgkin's disease occurs mainly in people between 15 and 40 or over 55. Non-Hodgkin's type cancer is much more common than Hodgkin's disease. Non-Hodgkin's lymphoma is a group of over 29 types of lymphoma. These are classified by the US National Cancer society as aggressive or fast multiplying or indolent, slow multiplying.
