Brief Summary

This study is being carried out to better understand how different types of mastectomy surgeries affect women's recovery, satisfaction, and overall well-being after breast cancer surgery and reconstruction. There are different ways to perform a mastectomy. In some patients, a nipple-sparing mastectomy may be suitable, where the nipple and surrounding breast skin are preserved. This approach allows for immediate breast reconstruction with an implant, which is placed at the same time as the mastectomy to restore the breast shape. A newer technique called robotic single-port nipple-sparing mastectomy uses advanced robotic technology to remove breast tissue through a small hidden incision at the side of the chest. This method may reduce scarring, pain, and recovery time, while preserving the appearance and sensation of the breast. However, while early studies suggest this technique is safe and effective, more evidence is needed to compare it directly with standard surgeries. This study will compare:

• Robotic nipple-sparing mastectomy
• Standard (open) nipple-sparing mastectomy We will assess patient satisfaction, body image, physical and emotional well-being, and surgical outcomes over 12 months following surgery. By taking part, you are helping researchers evaluate whether robotic and nipple-sparing approaches offer measurable benefits to patients. Taking part in this study will not affect your surgery or the care you receive. You will be given the best treatment available based on your individual medical needs, whether or not you decide to participate in the research.

Outcome Measures

Primary Outcomes (2)

• Secondary Outcome Measures

  * Surgical complication rates within 30 and 90 days, classified according to the Clavien-Dindo system. * Reoperation rates and need for unplanned return to theatre. * Length of hospital stay and drain duration * Operative time and estimated intraoperative blood loss. * Time to return to daily activities including work and physical exercise. * Aesthetic outcomes, assessed both by patient-reported satisfaction and by an independent panel review of standardized postoperative photographs. * Oncologic outcomes, including final pathology margin status and local recurrence (if applicable during follow-up). * Amount of residual breast tissue left on post operative MRI at 6 months in the different groups.

• Sex: female
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Women aged 18 years and older
