Video Details

The Urologic Oncology Fellowship at Memorial Sloan Kettering Cancer Center is the largest and oldest of its kind in the world. Established by Willet Whitmore, Jr., in 1951, the program continues a tradition of rigorous clinical and research training in urologic oncology.

Graduates of our Urologic Oncology Fellowship Program have become leaders in urologic oncology and chairs of departments at major medical centers in the United States and around the world.

Accredited by the Society of Urologic Oncology, the fellowship is structured to provide a two-year experience consisting of at least one year of clinical training and one year of research, with an option for a third year dedicated to research.
