Leukemia - what kind of disease?
Classification of leukemias
Forms of leukemia depend on the clinical course of the disease. The disease may begin suddenly, violently, leaking hard — this is typical for acute leukemia. The chronic form develops over the years, with periods of exacerbations and remissions, is more favorable in terms of therapy.
Depending on the prevalence of specific types of immature leukocytes are allocated to disease on the name of the cells:
- lymphocytic leukemia (lymphocytic leukemia) growth of lymphocytes;
- myeloid leukemia (myeloid leukemia) — excessive development of white blood cells of the granulocytic series (normal myelocytes in the blood should not be).
In addition, myeloid leukemia differs according to the detection of different types of myelocytes (promyelocytic leukemia).
For the doctor, correctly stated the diagnosis implies a certain clinical course of standard therapeutic measures, the prognosis of the disease.
Clinical manifestations of leukemia
Leukemia in adults differs from children's. In all cases, the disease is:
- the latent period (latent) and clinical manifestations are absent, the number of cells grows, but has not reached a critical level;
- period symptoms — the number of abnormal cells reached such high numbers that there is definite symptoms.
All signs of leukemia is commonly grouped according to the mechanism of occurrence:
- toxic — found different inflammatory processes in the form of pneumonia, sore throats, abscesses, pyelonephritis;
- haemorrhagic — characterized by extensive hemorrhages in the skin after injection, blood loss, increased bleeding gums, uterine bleeding;
- anemia is dominated by pale skin, shortness of breath, dizziness, low blood hemoglobin and red blood cells.

- complaints the patient has no, but the blood tests find changes;
- a lot of the symptoms, the patient's long-term survey all experts, but nothing in the blood can not be detected.
