Hodgkin's lymphoma, also known as Hodgkin's disease, is a type of lymphoma (cancer of the lymph nodes or 'glands') first described by Thomas Hodgkin in 1832. Hodgkin's lymphoma is characterized clinically by the orderly spread of disease from one lymph node group to another and by the development of systemic symptoms with advanced disease. Pathologically, the disease is characterized by the presence of Reed-Sternberg cells (a specific kind of cell seen on biopsies of the cancerous lymph nodes). Hodgkin's lymphoma was one of the first cancers to be cured by radiation. Later it was one of the first to be cured by combination chemotherapy. The cure rate is about 93%, making it one of the most curable forms of cancer.
