title: [Do biopsies and operations lead to formation of distant metastases? (author's transl)].
abstract: In medical and public literature the radiologist Krokowski states that diagnostic and operative procedures of cancer disease often stimulates the development of metastases. He believes that 30--90% of metastatic disease is the result of prior operations. Consequently he requires a prophylactic radiation therapy before any operative therapy is done. The authors question the theses of Krokowski since there is no detail presentation of this methods, which therefore cannot be repeated.
