Recurrence Rate Following Breast Conservation Surgery: A Retrospective Cohort Study

Margin assessment in breast surgery is multifaceted, requiring a personalized approach that considers tumor biology, systemic treatments, and pathological variability. Our findings support accepting a margin width of < 1 mm (no tumor on ink) for a single radial margin in invasive breast cancer, provided the other three radial margins are ≥ 1 mm. It reduces reoperations without compromising oncological outcomes. Integrating advanced intraoperative techniques and multidisciplinary decision-making will further optimize patient care and long-term outcomes.
