|موضوع: Hodgkin lymphoma الجمعة أكتوبر 23, 2009 7:11 pm|| |
is a disease in which malignant (cancer) cells form in the lymph system. Hodgkin lymphoma is a ype of cancer that develops in the lymph system, part of the body's immune system.
The lymph system is made up of the following:
* Lymph: Colorless, watery fluid that travels through the lymph system and carries white blood cells called lymphocytes. Lymphocytes protect the body against infections and the growth of tumors.
* Lymph vessels: A network of thin tubes that collect lymph from different parts of the body and return it to the bloodstream.
* Lymph nodes: Small, bean-shaped structures that filter lymph and store white blood cells that help fight infection and disease. Lymph nodes are located along the network of lymph vessels found throughout the body. Clusters of lymph nodes are found in the underarm, pelvis, neck, abdomen, and groin.
* Spleen: An organ that makes lymphocytes, filters the blood, stores blood cells, and destroys old blood cells. It is located on the left side of the abdomen near the stomach.
* Thymus: An organ in which lymphocytes grow and multiply. The thymus is in the chest behind the breastbone.
* Tonsils: Two small masses of lymph tissue at the back of the throat. The tonsils produce lymphocytes.
* Bone marrow: The soft, spongy tissue in the center of large bones. Bone marrow produces white blood cells, red blood cells, and platelets.
Age, gender, and Epstein-Barr infection can affect the risk of developing Hodgkin lymphoma. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor. Risk factors for Hodgkin lymphoma include the following:
* Being in young or late.
* Being male.
* Being infected with the Epstein-Barr virus.
* Having a first-degree relative (parent, brother, or sister) with Hodgkin lymphoma.
Pregnancy is not a risk factor for Hodgkin lymphoma.
Possible signs of Hodgkin lymphoma include swollen lymph nodes, fever, night sweats, and weight loss.
These and other symptoms may be caused by Hodgkin lymphoma. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems do not go away:
* Painless, swollen lymph nodes in the neck, underarm, or groin.
* Fever for no known reason.
* Drenching night sweats.
* Weight loss for no known reason.
* Itchy skin.
* Feeling very tired.
Tests that examine the lymph nodes are used to detect (find) and diagnose Hodgkin lymphoma.
The following tests and procedures may be used:
* Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's past illnesses and treatments will also be taken.
* Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following:
o The number of red blood cells, white blood cells, and platelets.
o The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.
o The portion of the sample made up of red blood cells.
