[Control of the success of radiotherapy in case of mastocarcinomas by means of mammography (author's transl)].

The authors present the experience about modifications of the mammographic data caused by X-ray irradiations which are described in three publications of other authors. Then they mention a first case observed by themselves in 1953 and give a detailed description and documentation of a new observation. In these cases and contrary to the reports of the other authors, a total regression of the tumor shadow in the radiogram was found. The first patient had demonstratable pulmonary metastases already when she was irradiated and the new patient died of cachexia. Before she died, metastases of the vertebral column were demonstrated by radiography which, according to the general and clinical findings, had certainly already existed at the beginning of radiotherapy. It had not been possible to find out what was the nature of pasty swellings lying near the tumor which had not been visible on the radiogram.
