Leukemias I. Definition: Leukemia appears to be a clonal disease resulting from the abnormal uncontrolled proliferation of a single stem cell from which a new clone of cells develops. For some unknown reason, these abnormal cells have a selective growth advantage over normal cells. Present data indicate that these cells are functionally different and biochemically abnormal. II.
These lymphocytes or the white blood cells are the main part of the lymphatic system that is affected. These lymphocytes more specifically the b type, or T-cells, lymphocytes begin to fail and are no longer able to fight the typical infections that occur in the body. In more severe cases Burkitt’s tumors can occur which causes severe infections to occur on any exposed part of the body due to the infected T-Cells being unable to hone in on any infections due to their being immature thanks to the rapid
Anemia is a blood condition where you have a low red blood cell count. Symptoms of Anemia are shortness of breathe, Fatigue, pail skin and nail beds, and also jaundice. The pain is called Sickle Cell Crises. Sickle Cell Crises is where the sickle red blood cells become “C” shaped and get stuck to other “C” shaped cell and cause a block in the blood flow in the capillaries to limbs and organs. The Sickle Cell Crises can cause acute or chronic pain.
Asbestos leads to cellular damage that disrupts the natural cell cycle. Once normal function of the cell cycle is lost, cells begin to divide and grow uncontrollably. These cells then accumulate into tumors that trigger Mesothelioma symptoms. Approximately 3% of women with cancer have Mesothelioma, and 5% of men with cancer have Mesothelioma. Current medical treatment options include chemotherapy, radiation, and surgery, and most patients choose to undergo a combination of these processes in order to increase their life expectancy.
Sickle cell anemia is an inherited disease. It affects some of your red blood cells by making them shaped abnormally. While normal red blood cells are round, Sickle cell anemia causes some of my red blood cells to be shaped like a sickle, or other deformed shapes. The doctors discovered that I had this disorder by performing "Hemoglobin electrophoresis". This disease does not affect me mentally.
Signs include chest pain, coughing, difficulty breathing, and fever. Aplastic crisis: This is when the bone marrow temporarily slows its production of RBCs due to infection or another cause, resulting in a serious drop in RBCs and severe anemia. Signs include paleness, fatigue, and rapid
Chemotherapy may be given to a cancer patient to keep the cancer from spreading or to prevent the cancer cells from dividing at a fast rate. Chemotherapy may also be given to a patient to help relieve symptoms such as pain from the cancer. Chemotherapy is a great discovery and has helped save many lives but it can be very invasive and cause unpleasant side effects. Chemotherapy is designed to kill any cells that are growing at a fast rate even if they are not cancerous, this can lead to great exhaustion and feeling sick. Nausea, vomiting, hair loss, and sickness are common side effects of Chemotherapy that cannot be prevented because every human body handles different drugs differently.
According to the American Cancer Society, for all stages of pancreatic cancer combined, the one-year relative survival rate is 20%, and the five-year rate is 4%. These low survival rates are attributable to the fact that fewer than 20% of patients' tumors are confined to the pancreas at the time of diagnosis; in most cases, the malignancy has already progressed to the point where surgical removal is impossible. A tumor may grow in the pancreas without signs and symptoms being noticeable at first, which can lead to the cancer being further
Current research from the National Institute on Aging indicates that the prevalence of Alzheimer’s disease doubles every five years beyond age 65. As the population ages the disease impacts agreater percentage of Americans. The incidence of the disease is rising in line with the aging population in America. 2012 Alzheimer’s disease Facts and Figures article provides a statistical resource for U.S. data related to Alzheimer’s disease, the most common type of dementia. An estimated 5.4 million Americans of all ages have Alzheimer’s disease in 2012.
Finally, blood is being coughed up, and chest pain and weight loss are in effect. Generally, by now the doctor has diagnosed it as lung cancer and has to determine the stage of cancer. If lucky enough, the cancer is treatable with chemotherapy or radiation therapy. Unfortuantely, nearly 440,000 people diasgnosed with lung cancer are not lucky and eventually die as a result ( Reducing). On the contrary, there are ways that tobacco is beneficial to people.
