Any of a group of cancers in which the cells of lymphoid tissue (found principally in the lymph nodes and the spleen) multiply unchecked. Lymphomas fall into 2 categories. If certain characteristic abnormal cells (Reed–Sternberg cells) are present, the disease is called Hodgkin’s disease. All other forms are known as non-Hodgkin’s lymphoma. (See Burkitt’s lymphoma; Hodgkin’s disease; lymphoma, non-Hodgkin’s.)
