Lymphoma, Hodgkin's, Non-Hodgkin's
Lymphoma is a general term for a group of cancers that originate in the lymph system. The two primary types of lymphoma are Hodgkin's lymphoma, which spreads in an orderly manner from one group of lymph nodes to another; and non-Hodgkin's lymphoma, which spreads through the lymphatic system in a non-orderly manner.
