A Friend Check out all of the information on this career. Physicians, M.D.s, are medical doctors who treat disease and injury. Physicians often evaluate and provide patient care in public or private hospitals, clinics, or private practices.
Physicians can prescribe medications for preventative and curative treatment.
Their work hours can be long and irregular. Although many physicians become internists, generalists, or family practitioners, most specialize in other medical fields. After three or four years of college, prospective physicians must attend medical school. Undergraduate requirements for admission to all medical schools include one year of basic chemistry, one year of organic chemistry, one year of biology, and one year of physics. Some medical schools also require course work in calculus, English, humanities, or social sciences.
