Lymphoma is a general term for cancers that develop in the lymphatic system.
- Hodgkin's disease, discovered by Thomas Hodgkin in 1832, is one type of lymphoma.
- All other lymphomas are grouped together and are called non-Hodgkin's lymphoma.
According to the U.S. National Institutes of Health, lymphomas account for about five percent of all cases of cancer in the United States, and Hodgkin's disease in particular accounts for less than one percent of all cases of cancer in the United States.
