Elizabeth Bundschuh on 10 Aug 13The cause of most cases of pediatric leukemia is not known, as most sufferers do not display any risk factors for the disease. However scientists have begun to understand how certain changes in DNA can cause leukemia. Cancer can be caused by mutation oncogenes, the genes that control when cells divide. A translocation between chromosomes 2 and 22 causes almost all cases of childhood chronic myeloid leukemia and childhood acute lymphocytic leukemia. Other genetic mutations can be inherited, however most of the mutations that cause leukemia develop after birth. Environmental factors, when combined with a genetic predisposition for leukemia, may trigger the disease. However the cause of most pediatric leukemia remains unknown.
