SUMMARY
Introduction: Non-palpable breast lesions are findings with not biologically specified importance, which can be responsible for development of cancer. Objective of this study is to present our experience with the diagnosis and the treatment of patients with non-palpable breast lesions at Department of Surgery of Faculty hospital in Nitra.

Material and methods: The authors present the diagnostic and the results of the treatment of patients with non-palpable breast lesions. They were hospitalized at Department of Surgery in Nitra since January 2014 until July 2017 and we used SNOLL method or wire guided excision under ultrasound control or digital stereotaxic.
Results: Since January 2014 until July 2017 there were 122 patients diagnosed with non-palpable breast lesions at Department of Surgery of our hospital. 76 (62.3%) of these patients were diagnosed with carcinoma. Wire Guided Localization was performed in 99 (81.1%) patients, sentinel node was found in 41 (33.6%) patients, using of the SNOLL method. From all of the patients the reoperation was conducted in 4 cases (3.3%) for close or positive margin status and in 3 cases (2.5%) for false negative perioperative sentinel biopsy.
Conclusion: The technique combining 99mTc-MAA (albumin-macro aggregate marked by 99Technecium) and nanocoloid is reliable localization method for non-palpable lesions and sentinel nodes. SNOLL is practical and oncological safe technique of excision subclinical lesion in combination with sentinel biopsy.
