Leukemia :: essays research papers
Leukemia à à à à à Leukemia strikes all ages and both sexes. In 1995 approximately 20,400 people died from Leukemia. The all time five year survival rate is 38%. This rate has gone to 52% in the mid 1980ââ¬â¢s. Approximately 25,700 cases were reported in 1995 alone(American Cancer Society-leukemia, 1995). à à à à à Leukemia is a form of cancer in the blood cells. Most forms of Leukemia occur in the white blood cells. These abnormal cells reproduce in large quantities and look and perform differently than normal cells(MedicineNet- leukemia, 1997). Right now the causes of Leukemia are unknown. Some studies have shown that exposure to high-energy radiation increases chances of contracting leukemia. Such radiation was produced in the atomic bombing of Japan during World War II. There is also enough energy in nuclear plants so strict safety precautions are taken. Some research shows that exposure to electric magnetic fields, such as power lines and electric appliances, is a possible risk factor. More studies are needed to prove this link. Some genetic conditions, such as Downââ¬â¢s syndrome, are also believed to increase the risk factor. Exposure to some chemicals is also suspected to be a risk factor. By learning the causes of leukemia treatment options will become available(MedicineNet-leukemia, 1997). There are many symptoms of leukemia. The symptoms of leukemia are the same for all the different types of leukemia. The acute types of leukemia, ALL and AML, symptoms are seen more quickly than in the chronic types of leukemia, CLL and CML, where symptoms do not necessarily appear right away. The symptoms are flu symptom, weakness, fatigue, constant infections, easily bleed and bruise, loss of weight and appetite, swollen lymph nodes, liver or spleen, paleness, bone or joint pain, excess sweating, swollen or bleeding gums, nosebleeds and other hemorrhages, and red spots called petechiae located underneath the skin. In acute Leukemia the cancerous cells may collect around the central nervous system. The results can include headaches, vomiting, confusion, loss of muscle control, or seizures. These clumps of cancer cells can collect in other various parts of the body(MedicineNet-leukemia, 1997 and American Cancer Society- leukemia, 1995). à à à à à Leukemia can be diagnosed in a number of ways. Blood work is commonly done in the laboratory. Different forms of blood work include checking the hemoglobin count, platelet count, or white blood cell count. X-rays are routinely done for treatment follow-up. Ultrasound is also used as a treatment follow-up. CT Scan is a special type of x-ray used as a detailed cross section of a specific area of the body. Bone marrow is routinely tested to examine progress of the disease. Spinal taps are also used in certain types of cancers.
