What are Medical Cities? International Medical Cities are MTM Partners, Hospitals, Physicians in the Global Health Care Network around the world. The concept of a medical or health city is often a misunderstood term. A cluster of hospitals, a holistic healthcare center, a large hospital sprawled across acres of land? Certainly, but it doesn't end here. In simpler terms, the difference between a hospital and a medical city is as vast as the difference between a corner shop and a mega-store. What you won't find at the shop, you will be certain to get at the store.
