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 the United States.

Etiology

The etiology of most lymphomas is not known. Rare types of lymphomas are caused by viruses. Burkitt's lymphoma, extranodal NK/T cell lymphoma and Hodgkin's disease are caused by the Epstein-Barr virus. Adult T-cell lymphoma/leukemia is caused by the HTLV-1 virus, endemic in parts of Japan and the Caribbean. Lymphoma of the stomach is often caused by the Helicobacter bacteria.
