What causes leukemia

Operation method

Chemical factor: This is because the patient has been exposed to chemicals for a long time, such as benzene, and the leukogenic effect of benzene is relatively positive. The acute leukemia caused by benzene is mainly acute myeloid leukemia and erythroleukemia. But this reason is not common.

Genetic factor: this pathogenic factor has not yet been proved. Clinically, it may be the cause of leukemia. Eight percent of leukemia patients have a family history of leukemia, which is a common cause and cannot be ignored.

Virus: If the patient suffers from other diseases in the early stage, such as some tumors, leukemia may occur at this time, because most of the homologous genes of vertebrates are source tumor genes, and the leukemia effect of RNA virus in mice, cats, chickens, cattle and other animals has been confirmed, and most of the leukemia caused by this type of virus belongs to T-cell type, So this is also one of the causes of leukemia.

Radiological factors: It was found very early that radiation workers (radiologists without protection), non leukemia patients receiving radiation therapy, such as spondylitis, are prone to leukemia. The incidence of leukemia among the survivors of the atomic bombing in Japan is higher than that of the population in other cities, with the highest incidence five years after the explosion. It is because radiation causes malignant changes in human hematopoietic cells.
