Safety and Feasibility of Robotic SP Nipple Sparing Mastectomy

This study is testing whether a nipple-sparing mastectomy (breast removal while preserving the nipple) can be done safely using a robotic surgical system. This approach may result in less visible scarring and better cosmetic outcomes compared to traditional open surgery. **You may be eligible if...** - You are a candidate for a nipple-sparing mastectomy based on your tumor's size and location - You are having a preventive mastectomy (for risk reduction) or being treated for early-stage breast cancer or DCIS (non-invasive breast cancer) - You are in good enough physical condition to tolerate surgery and anesthesia **You may NOT be eligible if...** - You have inflammatory breast cancer - The skin over your breast or the nipple area is involved with tumor - You have significant drooping of the nipple (Grade 3 or higher ptosis) - You are pregnant or nursing - You are a heavy smoker (more than 20 cigarettes per day) - You cannot safely receive general anesthesia Talk to your doctor to see if this trial is right for you.
