Cancer Research Assignment
Leukemia is a form of cancer found in the blood and the bone marrow, where more white abnormal cells are dividing quickly which could overtime outnumber the normal cells. Leukemia starts formation in the stem cells of bone marrow and develops when the blood stem cells in the marrow are abnormal. Overtime this rapid growth and division will cause the leukemia cells to overcrowd the normal blood cells, making it harder for the white blood cells, red blood cells and platelet to function. It begins by attacking and reducing the infection fighting white blood cells, making it harder for the body to repair itself and can lead to the development of other diseases, it disrupts the normal cell balance hindering the cells from performing their duties and when cancerous cells attack the bone marrow it causes numerous bone and joint pain. There are approximately over 223,000 leukemia patients in the U.S (The Survivors Club, 2011) and the survival of the patient depends on the phase of leukemia they are in, chronic leukemia patients are more responsive to treatment, the worst is the acute blast phase where the chance of survival is slim. The good news is the survival rate is a lot better than they were decades ago, new improvements on technology mean the chances of living 5 years or more are feasible. There are many different types of available treatments for leukemia such as chemotherapy where drugs are injected to try to contain the abnormal cells. Stem cell transplant uses high dose chemotherapy to eliminate bone marrow cancer cells so the marrow can be substituted with a transplant of new strong stem cells. In radiation therapy a large machine will carefully target the infected area of the body with radiation, hopefully damaging all the cancer cells in its path, in
some cases it is used to prevent the spread of the abnormal cells. Finally biological therapy uses the immune system and creates natural drugs to enhance the body’s...
