While both M.D.s and D.O.s may use all accepted methods of treatment, including drugs and surgery, D.O.s place special emphasis on the body's musculoskeletal system, preventive medicine, and holistic patient care. Most physicians specialize in one branch of medicine. Medical specialties for which there is training include internal medicine,pediatrics, obstetrics and gynecology, radiology, surgery, anesthesiology, pathology,ophthalmology, or family medicine.
Pediatricians, general and family practitioners, and general internists are often called primary care physicians since they are the first health professionals patients usually consult.
