The education needed to be a medical physician is medical school. Medical students complete 4 or more years of medical school (depends on the medical school's country) and usually attend a residency to specialize in a specific type of medicine for 3+ years and possibly a fellowship after that. Medical degrees that can be earned in medical school are a Doctor of Osteopathic Medicine degree (D.O.) (earned in the United States), the Doctor of Medicine degree (M.D.), or the Bachelor of Medicine/Bachelor of Surgery degree (MBBS/MBChB). The first half of the medical school curriculum usually centers on the medical sciences such as biochemistry, histology, pathology, microbiology, anatomy, etc., and the second half on clinical expertise.
