Non-Hodgkin's Lymphoma
What is non-Hodgkin's lymphoma?
Non-Hodgkin's disease is a type of lymphoma, which is a cancer in the lymphatic system. Non-Hodgkin's lymphoma causes the cells in the lymphatic system to abnormally reproduce, eventually causing tumors to grow. These lymphoma cells can also spread to other organs.
There are several types of non-Hodgkin's lymphoma, which are classified by how quickly they spread.
What is the lymphatic system?
The lymphatic system is part of the immune system, whose function is to fight disease and infections. The lymphatic system includes:
- lymph - fluid in which the lymphocyte cells are suspended.
- lymphatic vessels - thin tubes that carry lymph fluid throughout the body.
- lymphocytes - cells that fight infection and disease.
- lymph nodes - small, bean-shaped organs, found in the underarm, groin, neck, and abdomen, that act as filters for the lymph fluid as it passes through them.
What are the symptoms of non-Hodgkin's lymphoma?
The following are the most common symptoms of non-Hodgkin's lymphoma. However, each individual may experience symptoms differently. Symptoms may include:
- painless swelling of lymph nodes in neck, underarm, and groin
- fever
- night sweats
- fatigue
- weight loss
- itching of the skin
- recurring infections
The symptoms of non-Hodgkin's lymphoma may resemble other blood disorders or medical problems, such as influenza or other infections. Always consult your physician for a diagnosis.
What are the risk factors for non-Hodgkin's lymphomas?
Suggested risk factors for non-Hodgkin's lymphomas include the following:
- genetic disease of the immune system
- unprotected exposure to strong sunlight
- high-fat, low-fiber diet
- smoking
- excessive alcohol consumption
- environmental factors such as radiation, chemicals, and infections
- organ transplantation
- infections with human immunodeficiency virus (HIV) or human T-cell leukemia/lymphoma virus (HTLV-1)
- infections with malaria
- history of infectious mononucleosis (caused by an infection with the Epstein-Barr virus)
- Helicobacter pylori (H. pylori) bacterium, which has been identified as a cause of stomach ulcers
What causes non-Hodgkin's lymphoma?
No specific cause has been identified.
How is non-Hodgkin's lymphoma diagnosed?
In addition to a complete medical history and physical examination, diagnostic procedures for non-Hodgkin's lymphoma may include the following:
- additional blood tests and other evaluation procedures
- x-rays of the chest, bones, liver, and spleen - a diagnostic test which uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.
- lymph node biopsy - a procedure performed to remove tissue or cells from the body for examination under a microscope.
- bone marrow aspiration and biopsy - marrow may be removed by aspiration or a needle biopsy under local anesthesia. In aspiration biopsy, a fluid specimen is removed from the bone marrow. In a needle biopsy, marrow cells (not fluid) are removed. These methods are often used together.
- lymphangiograms - x-rays of the lymphatic system.
- computed tomography scan (also called a CT or CAT scan) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays.
- ultrasound (also called sonography) - a diagnostic imaging technique which uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Ultrasounds are used to view internal organs as they function, and to assess blood flow through various vessels.
Treatment for Non-Hodgkin's Lymphoma
Specific treatment for non-Hodgkin's lymphoma will be determined by your physician based on:
- your age, overall health, and medical history
- extent of the disease
- your tolerance for specific medications, procedures, or therapies
- expectations for the course of the disease
- your opinion or preference
Treatment may include:
- radiation therapy
- chemotherapy
