Neil M. Iyengar, MD
Breast Medical Oncologist
My Role at MSKWe 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
- Associate Attending Physician
I am a medical oncologist and clinical investigator with a practice dedicated exclusively to the care of patients with breast cancer. As a member of our multidisciplinary team of specialists, I treat patients with an individualized and multifaceted approach based on cutting-edge technology and the most up-to-date research.
My practice is focused on providing patients with state-of-the-art care plans using advanced technologies and innovative strategies to treat breast cancer while also providing support for general well-being, such as nutrition and exercise. Ultimately, I am dedicated to providing clear communication and understandable information regarding standard therapies as well as new and exciting research options so that patients are empowered to make informed decisions about their care.

My research investigates the links between metabolic health and cancer. I work with a highly productive team composed of clinical and laboratory scientists at Memorial Sloan Kettering, Weill Cornell Medical College, and the Rockefeller University, where I hold a joint research position. Our team has established inflammation in the breast to be a key contributor to obesity-related breast cancers. As obesity rates are on the rise in the United States and worldwide, we are seeing an increase in obesity-related cancers. We have shown that inflammation in the fatty tissue of the breast and at other anatomic sites occurs in most obese and overweight individuals and even in some individuals who are normal weight. Therefore a key component of my research program is the development of clinical trials — including diets, exercise, and medications — that aim to prevent obesity-related cancers as well as improve outcomes in patients with fatty-tissue inflammation.
A breast medical oncologist is a cancer doctor who specializes in breast cancer.
