[Mammary tumor puncture with fine needle].

Breast cancer is the second malignant tumor that affects women in our population. The fine needle biopsy is a sensitive and specific technique. The purpose for this study was to show our experience at our institution. The fine needle biopsy was performed in 22 patients with diagnosis of breast tumor; all were surgically treated. In all the cases the initial cytology showed a high correlation with final histology findings. There were no complications. It was concluded that with an adequate fine needle biopsy technique, results correlate well with histopathologic study, with high sensitivity and specificity. This technique is easy to perform, with a low cost, and it may be considered as an useful tool in the study of patients with breast tumors.
