OBJECTIVE: The objective of this work was information of genetic characteristics of tumor, determined by methods such as mamma print identifies more adequately the risks and treatments for patients. In this work we report our experience with the use of mamma print. METHOD: Analyzing the results of 16 patients whom met the selection criteria. RESULTS: 56.2 5% of the cases were in the test reported insufficient, 25 % high risk and 18.75 % low risk. 75% of patients were older than 50 years. In these patients were not identified high-risk tumors, mean while in patients less than 50 years 50 % of the tumors corresponded to the high risk group. In 62.5 % of patients the lesion was less than 10 mm (T1b), while 37.5 % were T1c group. In the group of low risk patients, axillaries nodes were not identified to the U.S., by contrast 50 % of patients at high risk were identified and accordingly a fine needle punting was performed, with results negative for metastases. In none of the patients in low-risk & group metastases was identified in the postoperative histological evaluation, however in 75 % of the group of at high risk patients was identified axillaries node metastases. CONCLUSION: Determining of the characteristics and genetic alterations in breast cancer has fundamental importance for a better identification of groups of low and high risk and to determine the best treatments
