Andreas Giannakou, MD
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.

Get to Know Me
I am a board-certified breast surgeon who treats people with breast cancer. I see patients at Memorial Sloan Kettering Commack on Long Island, and perform surgery at the Josie Robertson Surgery Center in Manhattan.
I specialize in advanced breast surgery techniques including skin-sparing mastectomies, nipple-sparing mastectomies, and oncoplastic surgery. Oncoplastic surgery combines traditional breast cancer surgery with plastic surgery techniques by using hidden incisions and rearranging breast tissue to achieve the best possible cosmetic results for patients.
I am passionate about helping and supporting my patients throughout their treatment journey. I make it a priority to take the time to understand their needs and answer their questions during every visit. My goal is to make my patients feel comfortable and confident with their decisions and guide them at every step. After I provide them with the most up-to-date information about their diagnosis and my recommendations, we work together to make decisions about a treatment and care plan that best fits their individual needs.
My research focuses on translating the results of important clinical trials that are potentially practice changing. I am investigating the best and safest ways to potentially implement those findings and incorporate them into everyday clinical practice. I am also focusing on innovation and using the power of artificial intelligence to improve diagnosis, treatment, and care delivery for patients.
When I’m not seeing patients, I enjoy spending quality time with my family and loved ones. Cooking with my family is one of my favorite things to do. I also love to stay active by working out and playing tennis and I love painting on canvas and exploring new art techniques.
I'm a breast surgeon, which is a doctor with special training in breast surgery.

Disclosures
Members of the MSK Community often work with pharmaceutical, device, biotechnology, and life sciences companies, and other organizations outside of MSK, to find safe and effective cancer treatments, to improve patient care, and to educate the health care community. These activities outside of MSK further our mission, provide productive collaborations, and promote the practical application of scientific discoveries.
MSK requires doctors, faculty members, and leaders to report (“disclose”) the relationships and financial interests they have with external entities. As a commitment to transparency with our community, we make that information available to the public. Not all disclosed interests and relationships present conflicts of interest. MSK reviews all disclosed interests and relationships to assess whether a conflict of interest exists and whether formal COI management is needed.
