Lymphoma is a variety of cancer that originates in lymphocytes or, more rarely, of histiocytes.
Collectively, these cell types form the reticuloendothelial system and circulate in the vessels of the lymphatic system.
Just as there are many types of lymphocytes, so there are many types of lymphoma.
Lymphomas are part of the broad group of diseases called hematological neoplasms.
Because the lymphatic system is part of the body's immune system, patients with weakened immune system, such as from HIV infection or from certain drugs or medication, also have a higher incidence of lymphoma.
