Doctor writing on notepad


Earning your Doctor of Medicine (MD) degree is a huge accomplishment, but it is not the end of the journey. New MDs must decide what kind of physician they want to be, and how much time they want to dedicate to post-graduate training.

The American Association of Medical Colleges (AAMC) lists more than 135 medical specialties and subspecialties available for graduating physicians to pursue, and each one requires a residency of between three and eight years. Some specialties also require further years of fellowship study. To help students decide which area may fit them best, Ross University School of Medicine (RUSM) has developed in-depth articles on the major medical specialties. Each specialty is unique, and deciding on one may be the second biggest career decision—after deciding to become a physician—that you will ever make.
