The causes of infantile leukemia are not fully understood and may be related to genetic, physical, chemical, biological factors or other blood diseases.
1. Genetic factors: The most important cause of infantile leukemia is heredity. If the mother’s white blood cells are abnormal, the baby may also have abnormal white blood cells after birth, which may induce the disease.
2. Physical factors: if a woman is often exposed to strong radioactivity during pregnancy, including X-rays, γ-rays and other ionizing radiation; studies have shown that large-area and high-dose irradiation can lead to bone marrow suppression and a decline in the body’s immunity, as well as DNA mutation, breakage and recombination, leading to leukemia.
3. Chemical factors: years of exposure to benzene and organic solvents containing benzene are related to the occurrence of leukemia; ethylenediamorpholine has a very strong chromosomal aberration-causing and leukemia-causing effect; alkylating agents and topoisomerase I inhibitors in antitumor drugs can also lead to leukemia.
4. Biological factors: mainly viral infection and abnormal immune function.
5. Other leukemias: certain blood diseases may eventually develop into leukemia, such as myelodysplastic syndrome, lymphoma, multiple myeloma, paroxysmal sleep hemoglobinuria and so on.
The presence of the above factors should be promptly consulted to clarify the specific cause and follow the doctor’s instructions for treatment.
