Leukemia Disease

Commonly known as blood cancer leukemia is a malignant tumor of hematopoietic tissue, which is due to abnormal differentiation of hematopoietic stem cells, resulting in bone marrow and systemic organ tissue filled leukemia cells, normal hematopoietic function decreases gradually produce a variety of disease and death.The fatality rate of leukemiaAccording to statistics, there are 100,000 people worldwide every 2-9 people suffering from leukemia, from infants to the elderly in there. And sub-acute and chronic types of leukemia, acute if not treated in time, can be killed within a few months, chronic although can live for several years, but its cost of treatment and care efforts, will be a heavy burden on the family.The main symptoms of leukemiaSymptoms of acute leukemiaOccurs in children and youth.Illness sharp, menacing.Due to continued cold or menorrhagia, was found.Sudden high fever to 39-41 ° C, and is accompanied by chills, night sweats, weight loss, or weakness, pain and other symptoms.Often recurrent infections stomatitis, gingivitis, tonsillitis, pneumonia, otitis media or dermatitis.Sepsis or bacteremia.Non-traumatic fracture occurs.Unprovoked subcutaneous, oral mucosa, gums and nasal, etc., repeated bleeding.Headache, nausea, insomnia and irritability, at this time may have been complicated by intracranial hemorrhage. Severe cases can cause paralysis, coma and even death.Bone pain, lymph nodes, liver and spleen.Symptoms of chronic leukemiaOccur in the elderly.Malaise, fever, sweating or night sweats.Upper left abdominal discomfort, swelling feeling.Pain or pain in the limbs.Skin, gums or nose, etc., often unexplained bleeding. Women increased by the amount of unknown causes.Accompanied by systemic portion of superficial lymph nodes.Anemia, pallor, loss of appetite.Pathogenesis of leukemiaCausation of leukemia is unknown so far, but the medical community that the suspect with the following factors:Living environment long-term exposure to radiation or radioactive material, where the Japanese survivors of Hiroshima and Nagasaki, or receiving high-dose chemotherapy, the higher the probability of leukemia.Genetically abnormal child, such as Down's children, but also with a higher prevalence. In addition, the immune system is caused by abnormal leukemia motivating factor.Virus animal experiments confirmed that little mouse leukemia lines and some poultry caused by a virus. The EB virus, human T-cell leukemia virus and, were the medical community suspected leukemia.Diagnosis and treatment of leukemiaEarly symptoms of the suspected leukemia, it is important and timely to the hospital for blood and bone marrow examination. Blood tests can measure the degree of anemia, leukocytosis, or whether the amount of immature oocytes appear; bone marrow examination can detect the type of leukemia, in order to remedy. At present, because a variety of anti-cancer drug development, coupled with radiation therapy, chemotherapy, considerable progress, leukemia is no longer a terminal illness. Bone marrow transplant success rate getting higher and higher, which for patients with leukemia and severe blood brings a ray of hope.What is a bone marrow transplant? It is suitable for what disease?Skull, sternum, ribs, spine and pelvis and other bones of the sea-line-like tissue is bone marrow. It is the body to produce blood cells important organization. Bone marrow transplantation is not affected by normal bone marrow transplant patients to be destroyed, then the healthy bone marrow to inject intravenous drip way bloodstream. If successful transplant, the new bone marrow itself moves to the sponge-like tissue, and began to produce a normal blood.Prevention of white blood cells of the RoadPrevention of leukemia, in addition to the usual blood tests and symptoms through to alert outside urged people pay more attention to the prevention of the following way:Away from the Soviet nuclear power plant radiation leak, Hiroshima, Nagasaki, Japan after the nuclear explosion, a significant increase in the incidence of leukemia, confirming the risk of radiation induced leukemia. Often treated with radiation, X ray irradiation who morbidity also increased.Stay away from certain chemicals benzene, toluene and other chemical substances, suspected cause leukemia, people not long-term exposure.Away from long-term use of certain drugs anti-rheumatic drugs, antineoplastic agents, anti-inflammatory drugs and sulfa agents, can induce leukemia.Do not over-irradiated X-rays during pregnancy to avoid fetal suffering from congenital leukemia.Eat foods can enhance immunity eat milk, meat, soy and vitamin C-rich fruits and vegetables can prevent cancer.Strengthen the movement and life care in order to enhance physical fitness, weekdays should develop exercise habits, maintaining regular life, adequate sleep and avoid fatigue.
