Lymphoma refers to cancer of the lymphatic system, a network of lymph nodes connected by blood vessels that drain waste products and strain cancerous cells from the body. It occurs when lymphocytes, the white blood cells that attack infectious invaders, begin to multiply uncontrollably, producing cancerous cells that invade the body. The two main types of lymphoma are Hodgkin's lymphoma and non-Hodgkin's lymphoma. Symptoms include swollen lymph nodes, night sweats, and extreme fatigue. Treatment includes chemotherapy and radioimmunotherapy. Follow the links below to find WebMD's comprehensive coverage about lymphoma, its characteristics, symptoms, treatment, and much more.
