Localization of impalpable breast lesions and detection of sentinel lymph nodes through magnetic methods.

Purpose: The most commonly used technique for guiding the surgical removal of impalpable breast lesions is wire-guided localization (WGL). Potential complications of WGL include wire migration, wire transection, patient discomfort, and pneumothorax. Recently, another possibility for preoperative localization of breast lesions trough small steel seeds was developed.
