What is leukemia
Begins this kind of cancer Baltkon, usually, in the white blood cells.
Enjoys white blood cells ability to fend off and fight various infections and pollution. Grow these cells, in general, are very sound and divided according to the needs of the body. But, in the case of injury leukemia (leukemia), bone marrow produces in the body a very large amount of abnormal white blood cells (normal / abnormal), which can not functioning as it should.
The blood cancer (leukemia) is not a disease prevalent in children only. Flawhitad leukemia four major items and a wide variety of secondary items, only part of which is widespread in children.
That receive someone notification for diagnosing illness leukemia (leukemia) may raise feelings of anxiety and fear extreme, in what could be an important cancer treatment leukemia vehicle and complex, according to the type of leukemia (leukemia) and depending on many other factors are different. But, there are a variety of ways and a lot of resources that will help the patient cope with leukemia.
Questions and Answers
• What Mtabqhalansjh are required for a bone marrow transplant?
• Why stay patient sometimes after a bone marrow transplant in "isolation" after the transplant?
• What are the symptoms of leukemia?

Symptoms of leukemia
Symptoms vary blood cancer (leukemia) and vary, depending on the type of leukemia. However, the symptoms get common leukemia (leukemia) include:
• fever or shivering
• permanent fatigue, weakness
• frequent infections
• loss of appetite or weight loss

• Easy bleeding or the appearance of bruises
• shortness of breath during physical activity or when walking up stairs
• the emergence of points / small red spots on the skin (bled a local, topical)
• hyperhidrosis, especially in the night hours
• pain or sensitivity in the bone
Related symptoms unit quantity of abnormal blood cells (abnormal) and accumulation. One may overlook the initial signs and symptoms of leukemia disease (because it resembles the signs and symptoms of influenza (flu) or other common diseases).

The causes and risk factors for leukemia
Doctors classify leukemia, usually, in two ways:
1. By the pace of progress:
The classification is based first on the pace of progress of the disease.
Acute leukemia / dangerous - in acute leukemia, abnormal blood cells are primitive blood cells is sophisticated stubs (Blast). These cells are unable to do its job, and they tend to divide rapidly, so the disease worsens quickly. And requires acute leukemia treatment strong and tight, should start immediately.
Chronic leukemia (Chronic Leukemia) - This type arises from leukemia in adult blood cells (advanced). These cells divide and multiply, or accumulate more slowly and has the unusual ability to work, over a certain period of time. In some chronic leukemia items do not show symptoms of certain disease can remain hidden and undiagnosed for a few years.
2. By infected cells Type:
Second classification depends on the type of blood cells infected.
Lymphocytic leukemia (Lymphocytic Leukemia) - attacking this type of leukemia lymphocytes, responsible for the production of lymphatic tissue.
Alabiad myelogenous (Myelogenous Leukemia) - attacking this type of cells النقوية (Marrow cells) in the spinal cord.
Main kinds:
Types of leukemia (leukemia) Home is:
1.Disease appears when children and adults.
2.He is responsible for 75% of cases of leukemia in children.
3. Lymphatic leukemia chronic (or: lymphocytic leukemia chronic) (Chronic Lymphocytic Leukemia - CLL) - despite the fact that this type is very widespread and appears in adults, mainly, but a patient can enjoy a sense of well over several years without needing any treatment. It does not appear in children at all, almost.
4.
This gene produces a protein that is properly called tyrosine kinase (Tyrosine kinase) and scientists and doctors believe he is the one who can leukemia cells (leukemia) of evolution and reproduction. The patient suffers this type of blood cancer (leukemia) from a few symptoms, that originally appeared, over a period might take months or even years, before the start of the stage where the cells grow disease and multiply very quickly.
Other chronic defects in lymphoid cells:
As in CML, this group of diseases caused the emergence of leukemia chronic (Chronic leukemia), and through the production, excessive or scarce, the lymphoid cells.Group medical cases this could lead, eventually, to the emergence of leukemia in the spinal cord.

Etiology is clear:
Scientists do not know, yet, what are the real causes of disease leukemia (blood cancer). But, it seems that generates and develops as a result of the meeting of several factors and a variety of genetic and environmental factors, together.
These cells remain undeveloped, but able to reproduce. Because it is sophisticated enough, and is dead also happens to healthy cells, they accumulate and hinder the proper functioning of the vital organs in the body. In the end, abort this process of producing cells healthy and sound.
Attacking chronic leukemia blood cells are the most sophisticated. These cells multiply and accumulate more slowly, so the progression of the disease will be slower, too, but it could be fatal. Specialists still do not know exactly the real reasons for this process to occur.
In the end, created a lack of healthy blood cells and the former would receive health pollution, excessive bleeding and anemia (Anemia). The presence of a very large number of white blood cells that would affect the function of the fabric of bone marrow (Bone marrow tissue) and penetrate to other organs. When lead such a situation to death, it is usually as a result of blood loss sharply or as a result of the infection.
The following factors may increase the risk of some types of leukemia:
Cancer treatment - people who were subjected in the past to certain types of chemical treatment methods (Chemotherapy) or radiation therapy (Radiotherapy) to treat other types of cancer are susceptible to certain types of leukemia, after many years of treatment.
Genetics - it seems that certain genetic deviations that would affect the onset of leukemia. He discovered that certain genetic diseases, such as Down syndrome (Down syndrome), increase the likelihood of developing leukemia.
Exposure to radiation or to certain chemicals - people who have been exposed to very high levels of radiation, such as survivors of the atomic explosion or accident atomic reactor, are, in large part, to leukemia injury. Also, exposure to certain types of chemicals, such as benzene found in unleaded fuel and tobacco smoke and is also used in certain chemical industries, would also increase the risk of certain types of leukemia.
In all cases, the majority of people exposed to these risk factors or belonging to a particular risk group for injury leukemia, do not get it. And a large section of people with leukemia, were not among those who were exposed to these risk factors.

Diagnosis of leukemia
In most cases, doctors diagnosed leukemia disease (leukemia) through a normal blood test, before they have any symptoms appeared.
If this is the case, or if the person suffers from symptoms that may indicate his leukemia, it is likely to be subject to one or more of the following tests:
• physical examination
• blood tests
• immune phenotype (Immunophenotype)
• Examination of the cells (Cytogenic)

And there may be a need to many other tests to confirm the diagnosis and determine the type of leukemia and the degree of spread in the body.
Some types of blood cancer (leukemia) classified into levels, indicating the degree of seriousness and the ravages of the body. Determine the classification of the disease and تدريجه helps the physician in the development of leukemia treatment program optimization and most effective.

Treat leukemia
Unlike other types of cancer, the leukemia (leukemia) does not consist of a solid block Textile doctor can eradication and elimination surgery. Therefore, the treatment of leukemia is very complex.
And respect the complexity of key factors are: age, health status, type of leukemia (leukemia) Will spread to other organs in the body.
The methods of treating leukemia used to fight leukemia include:
• chemotherapy (Chemotherapy)
• kinase inhibitors (Kinase Inhibitors)
• Radiation therapy (Radiotherapy)
• planting pure (Bone Marrow Transplantation)
