Leukemia is a disease of the bone marrow that constantly in an abnormal white blood cells begin reproducing arise. Leukemia, which literally "white blood" in greek, if there is an excess of abnormal white blood cells in the blood. The disease usually starts in white blood cells. The blood-forming cells (hematopoietic) bone marrow make leukocytes to the body against infectious organisms such as viruses and bacteria to defend. When the cells reach the centralNervous system and build in the cerebrospinal fluid that support s the brain and spine can cause headaches and seizures.
Lymphocytes, which are found both in blood and the lymphatic system, coordinate the immune response and antibody production. If untreated, the surplus leukemic cells overwhelm the bone marrow to arrive in the blood and eventually invade other parts of the body, such as lymph nodes, spleen, liver and central nervous system (brain, spinal cordCable). In this way, the behavior of leukemia, other than that of other types of cancer that usually begin in major organs and ultimately spread to the bone marrow.
Causes of Leukemia
The general causes of leukemia:
We do not know what causes leukemia.
Very high radiation
If you think your child is at risk for leukemia talk with your doctor.
Chemotherapy and radiotherapy

Enlarged liver and spleen.
Weakness and fatigue.
Frequent infections.
Bone pain orTenderness.
Shortness of breath when you are physically active, like when climbing stairs.
Breathing Problems
The treatment of leukemia
The abnormal cells are killed by drugs. Chemotherapy may be taken orally, with firearms or given into a vein (intravenously).
Surgery to remove an enlarged spleen or a venous access (large plastic tube) to give medications and withdraw blood samples to be installed.
Radiation therapy to kill cancer cells by exposurehigh-energy radiation.
High-energy X-rays are used to kill the abnormal cells.
After radiation and chemotherapy kills the abnormal bone marrow, healthy bone marrow from a healthy donor to a patient administered through a vein. The healthy bone marrow to the patient's bones and healthy blood cells. The majority of children with leukemia did not need a bone marrow transplant.
Some people with leukemia choose to participate in clinical trials to test experimental treatments or newCombinations of known therapies.
