Magseed Enabled Long-Term Localization of Axillary Lymph Nodes

Summary

The purpose of this study is to provide prospective evidence that the use of Magseed/Sentimag in marking axillary lymph nodes and guiding surgical localization in patients with breast cancer following neo-adjuvant chemotherapy (NAC) is effective.
