When the examination is known that leukemia affects the lymphocytes or lymphoid cells, it is called lymphocytic leukemia. Whereas myeloid cell leukemia affecting as neutrophils, basophils, and eosinophils, called leukemia mielositik. From this classification, the Leukemia is divided into four types of designation ;
1. Acute Lymphocytic Leukemia [ALL]. Is the most common type of leukemia in children. The disease is also present in adults who primarily have 65 years of age or older.
2. Leukemia Mielositik Acute [LMA]. It is more common in adults than children. This type was formerly called nonlimfositik acute leukemia.
3. Leukemia Lymphocytic Chronic [LLC]. This often affects adults over the age of 55 years. Sometimes it also affects young adults, and almost none on children.
4. Leukemia Mielositik Chronic [LMC] often occurs in adults. Can also occur in children, but very little.
It is not certain, but there are some factors suspected to affect the frequency of occurrence of leukemia, such as:
1. Radiation. This is supported by several reports of research dealing with some cases of leukemia that is more frequent radiological Employees suffering from leukemia, Penerita with radiotherapy more often suffer from leukemia,
Leukemia incidence was found in atomic bomb survivors 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, drugs used for chemotherapy.
3. Heredity. 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 retrovirus, feline leukemia virus, HTLV-1 in Adolescents.
Symptoms of Leukemia
Generally differ between patients, however, can generally be described as follows:
1. Anemia. Patients will appear tired, pale and breathing fast [red blood cells under normal causes less oxygen in the body, resulting in the patient breathes faster to compensate for the fulfillment of oxygen deficiency in the body].
2. Bleeding. When platelet [blood clotting cells] are not reproduced with reasonable because it is dominated by white blood cells, then the patient will experience bleeding in the skin tissue [the number of red wiggler width / minor in the skin tissue].
3. Esophageal infections. White blood cells act as a protective immunity, especially against infectious diseases. In Patients with leukemia, white blood cells that form is not normal [abnormal] so it does not function properly. As a result, the body of the patient vulnerable to infection virus / bacteria, even by itself would reveal complaints of fever, white discharge from the nose [runny nose], and cough.
4. Bone pain and joints. This is caused as a result of the bone marrow [bone marrow] by pressing solid white blood cells.
5. Abdominal pain. Abdominal pain is also one indication of the symptoms of leukemia, where leukemia cells may collect in the kidneys, liver and bile that causes enlargement of these organs and give rise to 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 arm, neck, chest and more. Gland lympa duty filter the blood, leukemia cells can accumulate here and cause swelling.
7. Difficulty breathing [dyspnea]. The patient may show symptoms of difficulty breathing and chest pain, if this happens then it should immediately get medical help.
