Non-Hodgkin's Lymphoma Brief
This refers to any group of cancers of lymphoid tissue that multiply unchecked. These are found mainly in the lymph nodes and spleen. Non-Hodgkin's lymphomas vary in their malignancy according to the activity of the abnormal cells. Primitive cells, or those that are poorly specialized, are most malignant. They tend to take over the lymph nodes rapidly.
There is usually painless swelling of the lymph nodes in the neck or groin. The liver and spleen may enlarge. The lymphoid tissue in the abdomen may be affected, and in rare cases, cause pain and abdominal bleeding from the intestines. If other organs are involved, symptoms may range from headache to skin ulceration. Unless it is controlled, the disease progressively impairs the immune system, leading to death from infections.Non-Hodgkin's Lymphoma Site
