 (the other category of lymphoma) are not present. There are about 10 different types of non-Hodgkin's lymphomas, some slower- or faster-growing than others. Non-Hodgkin's lymphoma can affect children as well as adults. In most cases the cause is unknown, but an increased incidence has been observed in people who have been exposed to Agent OrangeAgent Orange,

, and some forms of the disease are frequently seen in people with AIDSAIDS
or acquired immunodeficiency syndrome,
fatal disease caused by a rapidly mutating retrovirus that attacks the immune system and leaves the victim vulnerable to infections, malignancies, and neurological disorders. It was first recognized as a disease in 1981.

The first symptom of non-Hodgkin's lymphoma is often a painless swelling of a lymph node in the neck, the groin, or under the arm. Other symptoms include fever, night sweats, itching, and unexplained weight loss. Diagnosis is made by laboratory study of tissue obtained by taking a biopsybiopsy
, examination of cells or tissues removed from a living organism. Excised material may be studied in order to diagnose disease or to confirm findings of normality. Preparatory techniques depend on the nature of the tissue and the kind of study intended.

Treatment depends on how far the disease has progressed. It may include external-beam radiation therapy, chemotherapy, or biological therapy (boosting the body's immune response to the disease). Rituxan, a genetically engineered drug involving monoclonal antibodiesmonoclonal antibody,

 transplantation is also sometimes used. In this technique, bone marrow (blood cell–producing tissue inside bone) is taken from the patient and treated to kill any cancer cells. The patient is then given very high dose chemotherapy designed to destroy the cancer; it also destroys the remaining bone marrow. After chemotherapy, the stored marrow is reinserted into the patient. In children, chemotherapy is the most common treatment.
