Wire-free localisation techniques for impalpable breast lesions

The mainstay of treatment for most breast cancers is breast conserving surgery. Impalpable breast lesions usually require image-guided localisation in advance of surgery, which facilitates the surgeon in identifying the target intraoperatively, allowing the area of disease to be excised with clear margins, while also ensuring that excess normal tissue is not removed.

In this regard, breast imaging teams have significant responsibility in ensuring that localisations are done accurately and in a way that is as helpful to the surgeon as possible. There are a variety of different types of breast lesions that require localising, including invasive tumours, lesions of uncertain malignant potential (B3), and areas of malignant calcification, as well as lymph nodes in the axilla.
