When cells in the lymphatic system grow at an abnormal rate, it creates a malignant tumor, Cancer. Hodgkin lymphoma and Non- Hodgkin lymphoma are both cancers that originate in white blood cells, in the lymphatic system. The system is responsible for fighting infection, bacteria, viruses, and removing damaged cells by producing lymphocytes (a type of white blood cell that is important to the immune system; they decide how the immune system will respond to infections or any an familiar organism). The system also communicates with the blood circulatory system by transporting lymph (a clear fluid that carries lymphocytes, waste, and excess fluid from tissues back into the blood system through the thoracic duct.) throughout the lymphatic system. Small vessels carry the lymph to the lymph nodes. There, the lymph is being filtered from unwanted and damaged organisms. The organisms are destroyed by the lymphocytes that are in the lymph nodes, and then the lymph goes back into the blood stream. Some lymph nodes are in the neck, groin, and under the armpits. The system also carries lipids from the intestine into the blood.
The lymphatic system includes the lymph and lymph vessels (very thin tubes). Through the lymph vessels, the lymph travels to different locations in the lymphatic system, and then goes back into the bloodstream. Lymphoid tissue includes lymph nodes. Lymph nodes are made of lymphocytes and other immune cells, and they filter the lymph before it goes back into the blood. The spleen filters blood and destroys old damaged blood cells and where white blood cells and platelets are kept. The thymus, an organ where T- cells mature, once they mature they can attack and destroy any damaged cell...

...y engineered molecules that are engineered to attach to a specific protein that is found only in B-cell. The immune system task is to fight invaders, however it does not always recognize the cancer as a harmful invader and does not attack it. The Monoclonal Antibody are directed to attach to a specific part of the cancer, marking the cancer cell as harmful and making it easy for the immune system to identify it and destroy it. Scientists are looking to to find out the reason lymphocytes turn into cancer, why they grow fast or live longer then they should. Once this is understood the focus will be on finding a cure for the disease. There are new drugs being tested on patients and studies are being done on how to improve steam cell transplant, and new drugs are being tested. A cure may be out of reach for time being but treatments and research are advancing every day.

- Rebecca Perl, from Maryland, has been diagnosed with non-Hodgkin's lymphoma in 1995. Rebecca has a two year old son and she is a health science reporter. Her body has not responded to the last six months of radiation and chemotherapy. Rebecca and her husband Tom are going to Omaha, Nebraska. At the University of Nebraska Medical Center Rebecca will receive a bone marrow transplant and a round of chemotherapy(Perl,1995). Rebecca and Tom head to Omaha, when they get to the hospital, the medical staff begin tests and blood work.... [tags: transplant, immune, hospital]

- Hodgkin 's Lymphoma Warren C. Ramos Carrington College ENG 113 Hodgkin 's Lymphoma It was the Christmas holiday season of 2013 and Uncle Sonny was healthy, happy, and full of vigor. Uncle Sonny was 58-year-old weighing 180 pounds and standing at a height of 5.10 inches. However, the family watched in utter desperation as Uncle Sonny’s body mass and height degenerate gradually to 92 pounds and 5.8 inches respectively. The most devastating scenario for the family was watching Uncle Sonny waste away on the hospital bed while looking hopeless and dull.... [tags: Lymphoma, Cancer, Hodgkin's lymphoma]

- Radioimmunotherapy A new innovative cancer treatment called Radioimmunotherapy or RIT joins conventional radiation therapy with immunotherapy. RIT uses monoclonal antibodies to target specific cancer cells and minimize damage to surrounding cells and tissue. Monoclonal antibodies (MAbs) are laboratory made immune proteins engineered to attach to antigens of specific cells. These antibodies mimic antibodies naturally produced as part of the immune system. Originally MAbs were made completely from mice cells and when these were introduced into the human body, the immune system would react against them.... [tags: Cancer Treatment Medical Science]

- ... Hodgkin’s disease is distinguished from other lymphomas by the abnormal Reed-Sternberg cell , named for the pathologist who first detected it which can be seen easily under a microscope. Hodgkin’s disease tends to spread from one cluster to the next and responds predictably t treatment. It usually starts in lymph nodes in the neck or under the collarbone, spreads into the chest, abdomen, and pelvis, spleen, lungs and bone marrow. Type and Classification of Burkitt’s lymphoma The classification of Burkitt’s lymphoma describes three clinical variants: Endemic (African), sporadic (the predominant type found in non-malarial areas, non-African), and immunodeficiency-associated.(3) These types...

- On December 16, my life changed forever. I was in my third semester of college and had just finished my last final exam. Having studied all night, I headed to the university game room to shoot some pool and relax. After a few games I felt painful spasms in my neck and shoulder. At first I thought it was a “pinched” nerve, and I tried to ignore it, but the pain just got worse. I wanted to go home, but I had promised my girlfriend we would meet. As I walked to her building the pain shifted to my chest and I grew short of breath.... [tags: essays research papers fc]

- Hodgkin’s Disease Cancers arising from the lymph nodes or other sites of lymphoid tissue are broadly termed lymphomas. This group of diseases is divided into Hodgkin’s disease and non-Hodgkin’s lymphoma. In both conditions, there is a replacement of normal lymphatic tissue by collections of abnormal lymphoma cells. The lymphatic system are a complex network of specialised cells and organs that defend the body against infection. Lymphatic organs include the bone marrow, spleen, thymus gland, lymph nodes, tonsils, adenoids, appendix and clumps of tissue in the small bowel.... [tags: essays papers]

- Lymphadenopathy is the term for swelling of the lymph nodes. These are the bean-shaped organs found in the underarm, groin, neck, chest, and abdomen. They act as filters for the lymph fluid as it circulates through the body. The most common site of lymphadenopathy are the cervical lymph nodes found in the neck. The lymphatic system is part of the immune system and functions to fight infections and disease. As infection-fighting cells and fluid build up, the lymph nodes enlarge to many times their normal size.... [tags: Lymphoma, Cancer, Lymph node, Lymphatic system]
