Diagnostic procedures used to confirm suspected non-Hodgkin's lymphoma include PET scans, gallium scans, and occasionally lymphangiograms. If lymphoma is diagnosed, it will be staged using the same system as for Hodgkin's disease.
Treatment will depend on the type and stage. It may be single agent or multiagent chemotherapy, radiation therapy, biotherapy, or a combination. Blood transfusions and bone marrow transplantation have shown efficacy for some types of lymphoma.
Patient care: major problems presented by the patient with non-Hodgkin's lymphoma include the management of side effects associated with treatment and the prevention of infection.

lymphomaOncology A malignant neoplasm of B or T lymphocytes, arising from a monoclonal, ie derived from a single progenitor cell, proliferation of lymphocytes; the proliferative process is considered lymphomatous in the appropriate clinical setting, given that not all monoclonal expansions are malignant Clinical Painless swelling of lymph nodes in neck, underarm, groin Prognosis Favorable in follicular lymphomas, especially cleaved, mixed and large non-cleaved cell types; some diffuse lymphomas–eg, small lymphocytic, cleaved cell, Burkitt's, non-cleaved cell and convoluted cell types, have OK-ish prognoses; Ls with poor prognosis include diffuse plasmacytoid lymphocye, mixed cell, mixed small noncleaved cell and large noncleaved cell types; advanced age, anemia and high mitotic activity are associated with a poor prognosis.

Staging of both Hodgkin and non-Hodgkin lymphoma is as follows: Stage I: involvement of a single lymph node or localized involvement. Stage II: Involvement of two or more lymph node regions on the same side of the diaphragm. Stage III: Involvement of several lymph node regions on both sides of the diaphragm. Stage IV: Involvement of extralymphatic tissue, such as the bone marrow.

non-Hodgkin lymphomaAbbreviation: NHL
Painless lymphadenopathy in two thirds of patients is the most frequent presenting symptom. Others have fever, night sweats, and loss of 10% or more of body weight in the 6 months before presenting with symptoms of infiltration into nonlymphoid tissue. Additional involvement is in peripheral areas such as epitrochlear nodes, the tonsillar area, and bone marrow. NHL is 50% more frequent in occurrence in men than in women of similar age. In most cases the cause of NHL is unknown, but patients who have received immunosuppressive agents have an over 100 times greater chance of developing NHL, probably because the immunosuppressive agents activate tumor viruses.
Specific therapy depends on the type, grade, and stage of the lymphoma. Combination chemotherapies, bone marrow transplantation, radiation therapy, and photochemotherapy may be given, depending on the specific diagnosis.

Patient discussion about lymphoma
Q. I would like to chat with someone w/any knowledge of fibromyalgia being treated with Methadone my best friend has severe fibromyalgia and has been treated with Methadone for the past several years. She has developed severe chronic anemia in these years. She now has lymphoma. I want to know if she is the only one and if methadone can affect bone marrow.
the Anemia is probably due to the Lymphoma. if not-her life is out of balance, she might changed her diet and may have shortage of iron or B12.
