[Aspiration cytology as method for the early morphologic diagnosis of recurrent breast cancer]

The results of aspiration cytology of suspicious indurations in patients following primary treatment of carcinoma of the breast are reported. Within 6 years 115 aspiration cytologies were performed in 84 patients. 63 recurrent cancers were diagnosed. 4 recurrences (6%) were not diagnosed by aspiration cytology. False positive tests were not observed. Aspiration cytology has a high accuracy and results in rapid morphological confirmation of a recurrence in early suspicious changes.
