Breast-Conserving Surgery Guided with Magnetic Seeds vs. Wires: A Single-Institution Experience.

Purpose: The aim of this study is to describe our initial experience using magnetic seeds (Magseed) to guide breast-conserving surgery in non-palpable breast lesions and compare the use of magnetic seed with wires to guide breast-conserving surgery in terms of clinical and pathological characteristics.

Methods: We performed a retrospective study including all breast-conserving surgeries for non-palpable breast lesions under 16 mm from June 2018 to May 2021. We compared breast-conserving surgeries guided with magnetic seeds (Magseed) to those guided with wires, analyzing tumor and patient characteristics, surgical time, and pathological results of the surgical specimens.
