Every medical school is good, and each medical school has its own professional field, which is enough to be called the best medical school. The best medical schools in the world have a ranking, and the top five are Harvard, Oxford, Stanford, Cambridge and Johns Hopkins. Please see the picture below for the rest.

Each college has its own top field. For example, Stanford University is top-notch in heart transplantation and tumor treatment, and it has a school-based medical center for students' clinical use. The University of London School of Medicine is the largest comprehensive cancer research center in Europe, and it is also the source of major medical advances such as adrenaline and immune system.
