Accuracy and feasibility of SentiMag technique for localization of non-palpable breast lesions.

Background: Non-palpable breast lesions are more frequent now than in the past due to the attention toward the mammary pathology and the screening diffusion; the marking of such lesions is very important for a successful surgery. The SentiMag System uses a magnetic marker that is inoculated transdermal in the breast through an 18-gauge needle.

Methods: Between April 1 and June 30, 2018, 16 patients with non-palpable breast lesions were selected and subjected to surgery using the SentiMag System in our Unit.
