In leukemia, there is an uncontrolled division of certain white blood cells. The cause is a series of changes in the genetic material (DNA) of the bone marrow cells, which produce these abnormal cells. These malignant bone marrow cells also no longer respond to signals to inhibit the production, when enough cells are produced. There are not only different, but far too many cells in the bloodstream. The proliferation of these abnormal cells, the production of normal blood cells is compromised.
Initially there is only an excess of abnormal bone marrow cells. Over time those cells are in the bloodstream and thus into the right bodies. Certain tissues can then filling up with abnormal cells. That is more to brands enlarged lymph nodes, an enlarged spleen and / or an enlarged liver.

There are a number of bone marrow diseases that are closely related to acute or chronic leukemia. One is the myelodysplastic syndrome. This syndrome includes a number of diseases where the function of stem cells is disrupted. There are enough cells then produced which then can not function properly. The disease can pass within a few years in acute leukemia.
The myelodysplastic syndrome is mainly found in middle age.

Leukemia derived from the Greek leukos-white, blood-haima. Leukemia (blood cancer) is a type of cancer that attacks cells, white blood cells produced by bone marrow (bone marrow). Bone marrow or bone marrow in the human body produces three types of blood cells including white blood cell (functioning as an immune system against infection), red blood cells (carry oxygen function into the body) and platelets (small part of the blood cells that help blood clotting process ).
Leukemia generally appear in a person since the days of small, bone marrow without obvious cause has been producing white blood cells do not develop normal or abnormal. Normally, white blood cells to reproduce again when the body needs it, or there is a place for the blood cells themselves. The human body will give signs / signals on a regular basis when will the blood cell-reproduction is expected to be back.
The cause of leukemia Until now the cause of leukemia is not known with certainty, but there are several factors suspected to affect the frequency of occurrence of leukemia.
1. Radiation. This is supported by several reports from several research Leukemia case that the radiology staff more    often suffering from leukemia, Penerita with radiotherapy more often suffering from leukemia, Leukemia found on the  victims of the atomic bomb live events of Hiroshima and Nagasaki, Japan.
2. Leukemogenik. Several chemicals have been identified are reported to affect the frequency of leukemia, such as   environmental toxins such as benzene, inustri chemicals such as insecticides, medicines used for chemotherapy.
3. Hereditary. People with Down syndrome have an incidence of acute leukemia 20 times greater than normal people.
4. Virus. Some types of viruses can cause leukemia, such as retroviruses, feline leukemia virus, HTLV-1 in adults.
The signs of the disease symptoms caused leukemia generally differ between the patients, however, can generally be described as follows:
1. Anemia. Patients will soon appear tired, pale and breathing fast (red blood cells below normal causes less oxygen in the body, as a result the patient to breathe faster to compensate for the fulfillment of oxygen deficiency in the body).
2. Bleeding. When platelet (blood clotting cells) are not reasonable because terproduksi with dominated by white blood cells, then the patient will experience bleeding skin dijaringan (the number of wide red larvae / dijaringan little skin).
3. The infection attacked. White blood cells act as protective immunity, especially against infectious diseases. In leukemia patients, white blood cells are abnormal diterbentuk (abnormal) that are not functioning properly. As a result the body of the patient vulnerable to viral / bacterial, even by itself will reveal complaints of fever, white discharge from the nose (runny) and cough.
4. Bones and joints pain. This is caused as a result of the bone marrow (bone marrow) by pressing solid white blood cells.
5. Stomach pain. Abdominal pain is also one indication of the symptoms of leukemia, where the leukemia cells may collect in organs kidney, liver and bile that causes enlargement of body organs and timbulah pain. Abdominal pain can affect appetite loss of leukemia patients.
6. Swollen glands Lympa. Patients likely to have swollen glands lympa, whether it is under the arms, neck, chest and others. Lympa duty gland blood screening, leukemia cells can be collected here and cause swelling.
7. Difficulty breathing (dyspnea). The patient may show symptoms of difficulty breathing and chest pain, if this happens then have to get medical help.
Adapaun how to prevent it because the disease can not be transmitted leukemia. However, advisable to avoid the entry of chemicals into the body, such as dust, chalk, and others. Prevention of leukemia is to consume vitamin A, C, fresh fruits and vegetables rich in fiber.
