Leukemia, Its Types And Causes

Leukemia is something the causes of which are not limited to the environmental factors alone like in the case of cold. Although the cause is still not confirmed, speculation is that it may also have its roots in the genetic areas. Leukemia can be acquired due to various risks by an individual. There are some different types of leukemia. The types are categorized in relation to the white blood corpuscles (WBCs) and the kind of abnormality they grow with.

In one of the cases, there is a presence of immature WBCs in the blood of the leukemia affected person. These immature WBCs are known as blasts in the scientific terms and are generally not present in the healthy human beings. If in case a person has this type of leukemia, he / she are liable to have high numbers of such blasts in the bone marrow. The acute case is when the growth rate of these damaged and immature cells is high which leads to the forming the major chunk of the WBC count in the blood stream to be of bad quality. Because they are immature, they serve no purpose are non-functioning. As in the case chronic leukemia, the patient's bone marrow is able to produce both the immature and the mature cells which thereby results in a slow deterioration rate of the blood components.

Leukemia varies from people to people according to their age group. People belonging to the age group of below 15, i.e. children are at a risk of suffering from lymphocytic leukemia whereas the adults can be victim to myelogenous leukemia. In both the kinds, the immature WBCs are produced in high rates than the normal cells which cause the immune system strength to fall. This happens because of not only the reduced concentrations of the fully grown and functional WBCs but also due to they becoming ineffective due to their functionality being reduced due to overcrowding.

The tests for leukemia can be conducted by checking the blood sample from the subject for the levels of white blood corpuscles. Because of the high rate at which they are produced, the quantity found would only be on the higher end.

The causes to leukemia have been linked to the prolonged exposure to various radiations. These radiations can be in the form of nuclear radiations or those emitted by the chemicals in a factory. People or laborers who work at sites wherein they are exposed to chemicals like benzene which have high reaction rate with the blood of the humans are known to be at much more risk of acquiring leukemia. Other less harmful chemicals like the ones used in the agricultural industry can also have the same effect if the exposure is for long durations even though it would a while before it really starts to show its true colors.

As far as the genetic reasons are concerned, scientists say that leukemia can be caused by the presence of abnormal chromosomes in the body of the patient. The abnormality can be because of inappropriate overlapping or the chromosomes switching places.
