[Breast needle-biopsy. Personal experience]

A personal series of 133 mammary needle biopsies is presented. Cytological specimens were obtained by aspiration via a thin needle from solid neoformations. The causes in which this form of examination was used are described and the extent to which the findings influenced surgery is explained. The method was found to be diagnostically sound and easy to perform. It may be regarded as a useful addition to other instrumental techniques in the diagnosis of breast swellings and in reducing the percentage of error.
