lymphoma, non-Hodgkin’s

lymphoma, non-Hodgkin’s A form of lymphoma in which malignant tumors arise in the lymphatic system. Abbreviated NHL. Several subtypes of cancer are classified as NHL, all of which originate in and spread via the lymphatic system. Symptoms of NHL depend on the location of the tumor, but can include swollen, but not painful, lymph nodes; gastric distress; skin problems; night sweats; unexplained weight loss; itching; and fever. Diagnosis is made via biopsy of a swollen lymph node, although an X-ray, a sonogram, a CAT scan, or an MRI may also be helpful. Treatment may include chemotherapy, radiation, bone marrow transplantation, stemcell transplantation, use of medication, and the use of monoclonal antibodies, depending on the age of the patient and the type of tumor.
