title: Radiation carcinogenesis.
abstract: Accidental or therapeutic exposure to radiation may induce tumors of various histologic types in human beings as well as in animals. Two tumors in this report arose in the organs which had been included in the field of radiation 32 and 8 years before, respectively. The author briefly reviews the literature, which abounds with references to radiation carcinogenesis.
