Radioactive seed localization is the preferred technique in nonpalpable breast cancer compared with wire-guided localization and radioguided occult lesion localization.

Objectives: Three commonly used techniques for localization of nonpalpable breast cancer are radioactive seed localization (RSL), wire-guided localization (WGL) and radioguided occult lesion localization (ROLL). In this study, we analysed the surgical margins of these three techniques.

Methods: Women diagnosed with nonpalpable breast cancer undergoing breast-conserving surgery with one of the above-mentioned techniques were retrospectively included.
