About this trial
MAGNETO is a French medico-economic study on preoperative localization in breast cancer surgery. The main objective is to conduct a cost-consequence analysis comparing magnetic clip localization with the use of metallic wires for the preoperative identification of non-palpable breast lesions. The choice of localization method is left to the physician's and center's discretion. The study is non-interventional (with only questionnaires and data collection), prospective, and multicenter, with patient follow-up lasting up to six months after breast surgery.
