People do not get leukemia for no reason, but in the vast majority of patients there are no obvious predisposing factors in daily life. Although the cause of leukemia is still not well understood, it is generally accepted that the development of leukemia is a complex process. The body is subjected to various events in daily life that result in genetic abnormalities and chromosomal alterations. When the genetic abnormalities and chromosomal changes reach a certain quality and quantity, leukemia will develop. Some of the events that occur in daily life include specific types of viral infections, prolonged exposure to radiation, prolonged exposure to chemicals containing benzene, and frequent exposure to hair dyes. All of the above factors can be involved in the development of leukemia as striking factors for the organism.
