Giacomo Montagna, MD, MPH
Breast Surgeon
We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

About Me
- Director, Rare Breast Cancer Program, Department of Surgery
I am a breast surgical oncologist who specializes in the treatment of benign and malignant breast diseases. I have a particular clinical and research interest in rare types of breast cancer, such as metaplastic breast cancer. I perform all types of breast and axillary surgery and I have specific training in oncoplastic breast surgery (both nipple sparing mastectomy and breast conservation techniques).
I see patients at Memorial Sloan Kettering Cancer Center’s Evelyn H. Lauder Center in New York City and at MSK Bergen.
I work in a multidisciplinary team that includes colleagues from radiology, pathology, plastic surgery, medical oncology and radiation oncology. Our goal is to deliver the highest quality of care by making a cohesive treatment plan tailored to our patients, their disease and their needs.
