non-Hodgkin lymphoma (NHL)


A group of related lymphomas (cancer that starts in immune cells of the lymphatic system) that are not Hodgkin lymphoma.

There are many different types of non-Hodgkin lymphoma. They are grouped by the lymphocyte (a type of white blood cell) they start in. B-cell lymphomas start in B cells (a type of white blood cell that makes antibodies to fight bacteria, viruses and fungi). T-cell lymphomas start in T cells (a type of white blood cell that helps control immune response, fight infection and destroy abnormal cells, including cancer cells).
