Non-Hodgkin's lymphoma is a type of cancer that originates in the lymphatic
system. It is estimated to be the sixth most common cancer in the United States.
The lymphatic system is part of the body's immune system and helps fight
infections and other diseases. In addition, the lymphatic system filters out
bacteria, viruses, and other unwanted substances.
The lymphatic system consists of the following:
Lymph vessels: These vessels branch out throughout the body similar to blood
Lymph: The lymph vessels carry a clear fluid called lymph. Lymph contains
white blood cells, especially lymphocytes such as B cells and T cells.
Lymph nodes: Lymph vessels are interconnected to small masses of lymph
tissue called lymph nodes. Lymph nodes are found throughout the body.
Collections of lymph nodes are found in the neck, underarms, chest, abdomen, and
groin. Lymph nodes store white blood cells. When you are ill and the lymph nodes
are active, they will swell and be easily palpable (your doctor can feel them
when she examines you).
Additional parts of the lymphatic system: The tonsils, thymus, and spleen
are additional components of the lymphatic system. Lymphatic tissue is also
found in other parts of the body, including the stomach, skin, and small
Because lymphatic tissue is found in many parts of the body, non-Hodgkin's
lymphoma can start almost anywhere.
Hodgkin's and Non-Hodgkin's Lymphoma: Differences and Similarities
Both Hodgkin's disease(sometimes referred to as Hodgkin's lymphoma) and non-Hodgkin's lymphoma are cancers that originate in a type of white blood cell known as a lymphocyte, an important component of the body's immune system. Both of these malignancies may cause similar symptoms, but the conditions themselves are different. The distinction between Hodgkin's disease and non-Hodgkin's lymphoma is made upon examination of the cancerous material (from a biopsy or aspiration of the tumor tissue). The type of abnormal cells identified in the sample determines whether a lymphoma is classified as Hodgkin's disease or non-Hodgkin's lymphoma.
There are many causes of chest pain, and while many are not serious, it may be difficult to distinguish among heart attack, pulmonary embolus or aortic dissection, and another diagnosis that is not life-threateni"...
