Breast Surgical Oncology Fellowship at The Mount Sinai Hospital

The Breast Surgical Oncology Fellowship at The Mount Sinai Hospital is a one-year subspecialty training program accredited by the Society of Surgical Oncology. Designed for physicians who have completed a general surgery residency, our program provides comprehensive training in the care of breast disease and is based at The Tisch Cancer Institute’s Dubin Breast Center.

The Dubin Breast Center provides fellows an immersive training environment within a state-of-the-art facility dedicated to the multidisciplinary management of benign and malignant breast disease. Program participants benefit from direct involvement in a wide range of services—spanning medical and surgical oncology, comprehensive breast imaging, infusion therapy, and interdisciplinary case conferences—all housed within a single, integrated center. Proximity to key resources such as MRI, radiation oncology, nuclear medicine, plastic and reconstructive surgery, and inpatient and outpatient operating suites further enhance hands-on learning and collaborative care opportunities.

With approximately 30,000 patient visits and more than 500 breast cancer surgeries annually at the Center, fellows receive exceptional clinical exposure to the full continuum of breast surgical oncology. Through The Tisch Cancer Institute, fellows also engage with a robust network of clinical, translational, and basic science investigators. These connections offer unique opportunities to engage in leading-edge clinical trials and research initiatives, supporting both patient care excellence and the fellows’ academic and professional development.

View Profile

To ensure exposure to all aspects of breast disease, six months of the fellowship are spent working in an apprenticeship fashion with Dubin Breast Center breast surgeons. During this time, the fellow is intimately involved with patients in the clinic and in the operating room from the time of initial presentation. The remaining six months of the fellowship are focused on medical oncology, breast imaging, breast pathology, radiation oncology, plastic and reconstructive surgery, cancer genetics, physical therapy and rehabilitation, palliative care, psycho-oncology, social work, and community outreach.

Within our multidisciplinary approach, fellows have regular interaction with breast imaging in the context of diagnosis and surgical planning; genetics in defining risk status; plastic surgery in terms of surgical execution; pathology as related to all aspects of patient care; and medical and radiation oncology for determining adjuvant and neo-adjuvant treatment.

Each fellow engages in one or two research projects designed with the goal of publication and national conference presentation. At the start of the program, our faculty collaborate closely with the fellow to identify areas of interest and align projects toward future academic and professional goals.

Previous fellows have presented their findings at meetings such as the Society of Surgical Oncology, the American Society of Breast Surgeons, and the American Society of Clinical Oncology, as well as the San Antonio Breast Cancer Symposium and the Miami Breast Cancer Conference. They have published in many prestigious publications, including the Journal of Clinical Oncology, Breast Cancer Research and Treatment, Annals of Surgical Oncology, Breast Diseases: A Year Book Quarterly, Archives of Surgical Oncology, and Cameron and Cameron’s Current Surgical Therapy.

In addition, our breast surgery oncology fellow plays an essential role in weekly multidisciplinary meetings at the Dubin Breast Center, presenting cases and giving talks on a wide range of topics, as well as partaking in ongoing didactic sessions given by faculty in all areas related to breast disease. The fellow also serves as a mentor to general surgery residents, particularly PGY-2 residents, as well as third-year and fourth-year medical students rotating on the breast surgical service.

The Breast Surgical Oncology Fellowship at The Mount Sinai Hospital accepts one fellow per year. For the 2025-2026 academic year, the salary is $110,565. All applicants must apply through the SSO Breast | National Matching Services.

Prior to beginning the program, the selected candidate must have completed a general surgery residency and be eligible for the American Board of Surgery. More information on how to apply, application materials, and deadlines is available at the Society of Surgical Oncology.
