[Radiography used during operations for biopsies of non-palpable lesions of the breast which have been suspected because of mammography (author's transl)].

In order to prove that non-palpable lesions of the breast that have been removed after suspicion from mammography have been removed completely it is appropriate to X-ray during the operation of biopsy in order to make a diagnosis. Tests carried out with the X Faxitron X-ray apparatus on 369 patients show that even X-ray departments that carry out mammography and do not have specialised equipment can with quite modest means use this reliable technique for diagnosis.
