Abstract
Of the 66, 276 Nagasaki atomic bomb survivors registered at the Scientific Data Center for the Atomic Bomb Disaster at the Nagasaki University School of Medicine, 140 were identified as having skin cancer from the records of 31 hospitals in Nagasaki City. From the cases of these survivors, a statistical analysis was made of the incidence of skin cancers by age, gender, histology and latency period in Nagasaki atomic bomb survivors. The results showed a high correlation between the incidence of skin cancer and distance from the blast hypocenter, and that the incidence of skin cancer in the Nagasaki survivors appears now to be increasing with exposure distance.
