[Procedure to be followed in cases of suspected changes diagnosed by means of mammography].

As a rule the diagnosis of larger focal lesions of the breast can be easily confirmed by biopsy. Intraoperative localization is more difficult, however, in lesions of below 5 mm diameter as measured by mammography or malignant alterations only indirectly indicated by mammography. Experience to date in 64 patients shows that specimen radiography provides immediate confirmation of large lesions detected by mammography and localizes the area for histologic examination. So far it has been found that precisely those biopsies that are performed as a result of indirect signs of malignancy or of small lesions are the most valuable contributing factor in the early diagnosis of breast cancer.
