- Specialty (medicine)
A specialty (or speciality) in medicine is a branch of medical science. After completing medical school, physicians or surgeons usually further their medical education in a specific specialty of medicine by completing a multiple year residency to become a medical specialist.
History of medical specialization
To a certain extent, medical practitioners have always been specialized. According to Galen, specialization was common among Roman doctors. The particular system of modern medical specialities evolved gradually during the 19th century. Informal social recognition of medical specialization evolved before the formal legal system. The particular subdivision of the practice of medicine into various specialities varies from country to country, and is somewhat arbitrary.
Classification of medical specialization
Medical specialties can be classified along several axes. These are:
- Surgical or internal medicine
- Age range of patients
- Diagnostic or therapeutic
- Organ-based or technique-based
The most important historically is the division into surgical and internal medicine specialties. The surgical specialties are the specialties where an important part of diagnosis and treatment is achieved through major surgical techniques. The internal medicine specialties are the specialties where the main diagnosis and treatment is never major surgery. Anesthesiology is classified as a surgical discipline, since it is vital in the surgical process, though anesthesiologists never perform major surgery themselves.
Many specialties are organ-based. Many symptoms and diseases come from a particular organ. Others are mainly based around a set of techniques, such as radiology, which was originally based around X-rays.
The age range of patients seen by any given specialist can be quite variable. Pediatricians handle most complaints and diseases in children that do not require surgery, and there are several subspecialties (formally or informally) in pediatrics that mimic the organ-based specialties in adults. Pediatric surgery may or not be a separate specialty that handles some kinds of surgical complaints in children.
A further subdivision is the diagnostic versus therapeutic specialties. While the diagnostic process is of great importance in all specialties, some specialists mainly or only perform diagnostic examinations, such as pathology, clinical neurophysiology and radiology. This line is becoming somewhat blurred with interventional radiology, an evolving field that uses image expertise to perform minimally invasive procedures.

List of specialties recognized in the European Union and European Economic Area
The European Union publishes a list of specialties recognized in the European Union, and by extension, the European Economic Area. Note that there is substantial overlap between some of the specialties and it is likely that for example "Clinical radiology" and "Radiology" refer to a large degree to the same pattern of practice across Europe.

List of North American medical specialties and others
In this table, as in many healthcare arenas, medical specialties are organized into the following groups:
- Surgical specialties focus on manually operative and instrumental techniques to treat disease.
- Medical specialties that focus on the diagnosis and non-surgical treatment of disease.
- Diagnostic specialties focus more purely on diagnosis of disorders.

Future Medical Specialties
Due to the large decline in men's use of healthcare services and facilities, there may be a future in creating a specialty dedicated exclusively to men's health and well being. It would be a conterpart to gynecology and would be most aptly named andrology.
The mean annual salary of a medical specialist is $175,011 in the US, and $272,000 for surgeons. However, because of commodity inflation, increasing negligent costs, steep price rise of rental, the annual salary range of a medical specialist varies and is not rising as fast as other professional pay.
The table below details the average range of salaries for physicians of selected specialties as of July 2010. Also given in the average number of hours worked per week for full time physicians (numbers are from 2003).

Specialties by country
Australia and New Zealand
Specialty training in Australia and New Zealand is overseen by the specialty colleges:
Specialty training in Canada is overseen by the Royal College of Physicians and Surgeons of Canada
Specialty training in India is overseen by the Medical Council of India which is responsible for recognition of post graduate training and by the National Board of Examinations. and education of Ayurveda in overseen by Central Council of Indian Medicine (CCIM), the council conducts u.g and p.g courses all over India, while Central Council of Homoeopathy does the same in the field of Homeopathy.
There are three agencies or organizations in the United States which collectively oversee physician board certification of MD and DO (allopathic and osteopathic) physicians in the United States in the 26 approved medical specialties recognized in the country. These organizations are the American Board of Medical Specialties (ABMS) and the American Medical Association; the American Osteopathic Association Bureau of Osteopathic Specialists (AOABOS) and the American Osteopathic Association; the American Board of Physician Specialties (ABPS) and the American Association of Physician Specialists. Each of these agencies and their associated national medical organization functions as its various specialty academies, colleges and societies.
Certifying Board National Organization Physician Type ABMS AMA MD and DO AOA-BOS AOA DO Only ABPS AAPS MD and DO
All boards of certification now require that medical practitioners demonstrate, by examination, continuing mastery of the core knowledge and skills for a chosen specialty. Recertification varies by particular specialty between every seven and every ten years.
In the U.S. Army, the term "medical specialist" refers to occupational therapists, physical therapists, dietitians and physician assistants, also known as allied health professionals. Also included in the term "medical specialist", but not in the term "allied health professional" are EMT/combat medics.
A survey of physicians in the United States came to the result that dermatologists are most satisfied with their choice of specialty, followed by orthopedic surgeons, radiologists, oncologists, plastic surgeons, and gastroenterologists. In contrast, primary care physicians were the least satisfied, followed by nephrologists, obstetricians/gynecologists, and pulmonologists.

- Interdisciplinary sub-specialties of medicine, including
- Occupational medicine – branch of clinical medicine which provides health advice to organizations and individuals concerning work-related health and safety issues and standards. See occupational safety and health.
- Disaster medicine – branch of medicine that provides healthcare services to disaster survivors; guides medically related disaster preparation, disaster planning, disaster response and disaster recovery throughout the disaster life cycle and serves as a liaison between and partner to the medical contingency planner, the emergency management professional, the incident command system, government and policy makers.
- Preventive medicine – part of medicine engaged with preventing disease rather than curing it. It can be contrasted not only with curative medicine, but also with public health methods (which work at the level of population health rather than individual health).
- Medical genetics – the application of genetics to medicine. Medical genetics is a broad and varied field. It encompasses many different individual fields, including clinical genetics, biochemical genetics, cytogenetics, molecular genetics, the genetics of common diseases (such as neural tube defects), and genetic counseling.
