Introduction
Many early-stage breast cancers are not palpable and thus must be localized before surgery. Detecting these lesions is crucial before they become clinically symptomatic to avoid morbidity and mortality. Nowadays, there are several new alternative techniques to traditional needle/wire localization available. These methods allow for better surgical margins, decreased costs and operating room delays, as well as improved patient satisfaction. The purpose of this study is to evaluate the nonradioactive inducible magnetic seed system Magseed (Endomagnetics Ltd, Cambridge, UK) for preoperative localization of nonpalpable breast lesions. To our knowledge, this report documents the first clinical experience with Magseed in Poland.

Material and methods
A single-institution case report of 10 women with nonpalpable breast lesions localized and excised by using the Magseed surgical guidance system between November 2017 and May 2018.

Results and conclusions
Magseed is an easy, sensitive and effective localization method. It is beneficial for oncoplastic outcomes and for scheduling efficiency, which overcomes many limitations of other localization methods. Surgical specimen margins were evaluated in 90% of cases as negative, with no additional re-excision. Only one patient with ductal carcinoma in situ had a positive tumor margin at the axillary side.
