James A. Fagin, MD
Endocrinologist
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
- Head of the Division of Subspecialty Medicine
I am a board-certified endocrinologist and internist, and I treat patients with thyroid cancer. I am a Member of the Endocrinology Service at Memorial Sloan Kettering, which has a tradition of excellence in both basic and clinical research in thyroid cancer, and in the care of patients with the disease.

Many patients with thyroid cancer can be successfully treated with surgery, and sometimes no further treatment is necessary. About a quarter of patients, though, have frequent recurrences. Since coming to Memorial Sloan Kettering, I have focused my research efforts on finding new treatments for patients with more-advanced thyroid cancer and more-aggressive forms of the disease.
An endocrinologist (EN-doh-krih-NAH-loh-jist) is a doctor with special training in endocrine problems. These disorders affect glands and organs that make hormones, and include diabetes, infertility, and thyroid, adrenal, and pituitary gland problems.
