A second peak of leukemia and increasing incidences of multiple primary cancers are recently evidenced among A-bomb survivors. The leukemia cases have a preceding phase called MDS, 50% of which develop into AML. A-bomb irradiation has caused life-long effects especially among young exposure population. Stem cells are injured at the DNA level, which eventually leads to birth of malignant cells. New topics also included are discovery of death certificates of early victims and a high incidence of leukemia among early entrants after A-bombing.
