Lymphoma is a general term for cancers that develop in the lymphatic system. Hodgkin's disease is one type of lymphoma. All other lymphomas are grouped together and are called non-Hodgkin's lymphoma. Lymphomas account for about 5 percent of all cases of cancer in this country. The Alvin & Lois Lapidus Cancer Institute offers screening, diagnostics and the full array of treatment options to detect and treat lymphoma.
