Background: fine needle aspiration biopsy is often applied in women operated of breast cancer. Objective: to analyze the results of fine needle aspiration cytology in women operated of breast cancer. Method: a cross-sectional analytical study was conducted in the Oncological Hospital Madame Curie. The universe included 440 operated women of breast cancer, of which 80 were sampled by probabilistic random sampling, from 2008 to 2010. The results of postoperative biopsy and fine needle aspiration cytologies were studied. Results: the 86,25 % of women were positive cytologies of neoplastic cells. Positivity of neoplastic cells in the results of mammography in 81,25 % was obtained, conventional infiltrating ductal carcinoma occupied the highest incidence, there was correspondence between the initial and final biopsy with diagnoses of infiltrating lobular carcinoma and conventional infiltrating ductal carcinoma to 16,6% and 83,3% respectively. In general, results showed the effectiveness this diagnostic method was developed which has great impact on therapeutic behavior and on treatment effectiveness. It was found statistically significant coincidence between aspiration cytology and postoperative biopsy. Conclusions: results of fine needle aspiration cytology can be considered as effective in obtaining diagnostic coincidence with postoperative biopsy in more than three-quarters of women. Only a minority were false negatives.
