Introduction. The atomic bomb survivors of Hiroshima and Nagasaki are a significant population for the study of radiation induced human leukemia. Whole body irradiation is most likely the cause of the leukemia caused by the atomic bomb radiation.[1] Follow-up of Japanese adult survivors of Hiroshima and Nagasaki have revealed abnormally high rates of cancer, persistent chromosomal aberrations in circulating lymphocytes, and lenticular opacities.3] Finally, children of atomic bomb survivors, who received exposure in utero ionizing radiation, had diminished stature, small head size, mental retardation, and subsequent seizures. [3] Study of the aforementioned groups has provided essential knowledge on the health effects of atomic bomb radiation.
Causes. Acute myelogenous leukemia is caused by damage to the DNA of developing cells in your bone marrow. When this happens, blood cell production goes wrong. The bone marrow produces immature cells that develop into leukemic white blood cells called myeloblasts. These abnormal cells are unable to function properly, and they can build up and crowd out healthy cells. In most cases, it's not clear what causes the DNA mutations that lead to leukemia.
