What Can Lead to Leukemia?

Although it’s impossible to diagnose precisely, what factors can lead to leukemia, there are certain circumstances which can finally result in its occurrence. These factors are connected with the outer world, and in some cases are dependent on genes.

The character and kind of this disease are directly connected with the production of white blood cells in the human’s organism. The marrow affected by leukemia starts making improper white blood cells. When white blood cells start forming in the marrow they overcome two stages. The first one is blast formation. Blast cells are the blood cells which have not reached the point of their maturity. The second stage is the formation of mature blood cells. It is normal for the first-stage cells to exist in the marrow, but these cells are not released to the blood system. However, in patients suffering from leukemia these cells are produced in abnormal quantity and are even found in human blood.

There are several kinds of leukemia so far determined by the modern medicine. They are subdivided to chronic and acute according to their character. In both types the marrow starts producing blasts in abnormal quantities, and these cells can’t function in a proper way to correspond to the body needs. However, in the acute character leukemia destroys the body at a fast pace, and in the chronic one it requires more time to affect the system.

The widely spread type of acute leukemia among people of middle age and older is acute myelogenous leukemia. In this form the disease leads to the rapid production of blasts in the marrow, which replace healthy white cells and start getting into the circulatory system. This causes blood system disorder. The chronic form of this type presupposes a gradual process of blast elevation in the narrow, and the excess production of white blood cells. Commonly the numerous white blood cells lead to anemia.

There is a type of anemia characteristic for children only. This type is called acute lymphocytic leukemia. The acute kind of this disease leads to considerable augmentation of blast cells in the marrow which quickly replace normal white blood cells in the blood system. Acute lymphocytic leukemia can be treated effectively if addressed appropriately and in timely manner. The chronic type of this disease is characterized by abnormal quantity of malfunctioning white blood cells, which are unable to address the infections and replace normal blood cells. The disease is commonly discovered when the doctor finds that white blood cell level is increased.

According to scientific studies, there are several environmental factors which may lead to leukemia. These are chemical intoxication, smoking, radiation and chemical substances used in agriculture. Leukemia is directly connected with the consequences of nuclear exposure. Acute leukemia may also result from pesticide exposure and herbicide contact.

Acute leukemia has been connected with smoking consequences for many years. A common cigarette contains more than 400 chemicals dangerous for health, among them benzene and aromatic hydrocarbons have strong link with leukemia. There are certain medications in chemical therapy which can lead to leukemia. Genetic changes, which are caused by chromosome abnormality, are also linked to leukemia.
