Doctors may specialize in one of 36 specialties.

Medical doctors may be doctors of medicine or doctors of osteopathy, and the field of medicine includes a wide variety of specialties and subspecialties for both types of doctors. By 2012, the American Board of Medical Specialties listed 36 major specialties and a number of subspecialties under several of them.

Surgeons and Anesthesiologists

Surgeons include the specialties of cardiac surgery, vascular surgery, orthopedics and neurosurgery. In some cases, there is crossover among specialties. An orthopedic surgeon may perform spinal surgery and a cardiac surgeon may perform some types of vascular surgery. Surgeons may specialize in adult or pediatric medicine -- or perform both. Although anesthesiologists don't perform surgery, their role in administering anesthesia is integral to the operative process.

Internal Medicine

Physicians who manage chronic disease and other non-surgical conditions include three large groups: pediatricians, internists, and family practice doctors, or general practitioners. Pediatricians focus on the care of children and adolescents; internists usually treat internal diseases of adults; and the general practitioner treats all age groups. The general practitioner may cross over into other specialties; some GPs perform minor surgery, deliver babies and set broken bones. Internist subspecialties include oncology, infectious disease, gastroenterology and sports medicine.

The Brain and Nervous System

Psychiatrists and neurologists specialize in diseases and conditions of the brain and nervous system. Psychiatrists treat mental health problems and manage diseases and conditions such as bipolar disorder, schizophrenia, depression and anxiety. Neurologists are concerned with the function of the brain and nervous system; they manage such conditions as epilepsy or multiple sclerosis.

Diagnostic Experts

In addition to interpreting radiological studies such as X-rays and mammograms, radiologists may perform interventional radiology, procedures that use radioactive dyes and X-ray machines to remove tumors, insert medical devices or open blocked arteries. Pathologists work in laboratories with samples of body tissue or blood, peering through microscopes to identify cancer cells or disease-causing organisms. Pathologists may also perform autopsies to determine causes of death. Physicians who specialize in nuclear medicine use radioactive isotopes that show pictures of the body parts to aid in diagnosis.

Doctors Without Patients

Medical doctors do not necessarily practice clinical medicine – in other words, they don’t necessarily take care of patients. Some medical doctors are strictly researchers in fields such as genetics, aerospace medicine or undersea medicine. Others may work in occupational, industrial or public health. Some doctors work as reviewers for insurance companies or in government jobs. Physicians in these fields may have started out in any number of specialties, and the work they do may not be related to their original training.
