What is the main cause of leukemia

Causes of Leukemia

Just like other types of cancer, leukemias arise as a result of gene mutations, i.e. changes in the genetic material. In leukemia, these changes are probably not hereditary, but are triggered accidentally in the course of life, due to certain predispositions or also by environmental influences. Ionizing rays and certain chemical substances are considered safe risk factors. Viruses and genetic factors are also discussed as possible causes. Leukemia is not contagious and cannot be passed on to other people.

Risk factors

Radiation exposure, benzenes and cytostatics are considered risk factors for the development of leukemia.


Leukemia is triggered by changes in the genetic make-up (mutations) in immature blood cells.


Diagnostic examinations can determine the type and cause of leukemia.
