Feasibility of a Standardized Fascial Plane Block Protocol for Breast Cancer Surgery

The goal of this observational study is to evaluate the feasibility of a standardized locoregional anesthesia protocol for patients undergoing breast cancer surgery under procedural sedation or adjunctive hypnosis. The main questions it aims to answer are: * Can breast cancer surgery be successfully completed using this standardized anesthetic protocol without conversion to general anesthesia? * Is this standardized protocol feasible to implement in routine clinical practice, based on patient acceptance, protocol adherence, anesthesia induction time, patient and surgeon satisfaction, perioperative complications, and reasons for conversion to general anesthesia? Participants will: * receive the standardized locoregional anesthesia protocol, combined with either procedural sedation or adjunctive hypnosis, as part of their routine clinical care; * allow the research team to collect information from their medical records regarding the anesthesia and surgical procedure; * complete a short satisfaction questionnaire before hospital discharge
