Mr Yamaguchi died on Monday morning from stomach cancer, according to Japanese newspapers. It is not clear if the cancer is related to his exposure to radiation...
Hmmm. He was 93 and August 1945 was over 64 years ago.
Maybe he was a smoker and that's what caused it.../s
Radiation exposure can also increase the probability of contracting some other diseases, mainly cancer, tumours, and genetic damage.
