[Iatrogenic radiogenic tumors. Observations on the incidence of tumors in the irradiation field following x-ray therapy].

A report is given on 18 patients with malignant tumors in the region of prior irradiation fields after a period of 28 years on an average. The irradiation was given because of malignant tumors in eight cases and for benign diseases in nine cases. The malignant tumors induced by ionizing radiation of the skin are often seen in multiple localisation. The risk of radiation induced cancer is given after irradiation for gynecological disorders and disorders of the superficial skin. The problem is discussed with the relevant literature.
