The goal of this comparative study is to learn how different surgical methods affect nipple and skin sensation after nipple-sparing mastectomy (NSM). The study will compare three types of NSM: conventional, endoscopic, and robotic. The main question it aims to answer is: How much nipple sensation do participants keep after each type of surgery? Researchers will also look at surgery-related complications, patient-reported outcomes like body image and quality of life, and tissue analysis to see if there is a link between nerve structures and sensation. Participants will: Have NSM using one of the three surgical approaches Receive breast reconstruction with an implant during the same surgery Complete nipple sensation tests before and at 1, 3, and 6 months after surgery Answer surveys about their quality of life and body image Provide surgical tissue for analysis (as part of the planned procedure)
