Physician in 1619: The plague doctor's beaked mask appears

Training now runs to roughly a decade past secondary school in most countries, and pay, licensing and status vary enormously by nation — a hospital consultant in England, a private internist in the United States and a rural general practitioner in India do the same job differently. The newest pressure is diagnostic software: some AI systems already match or beat junior physicians on standardized case tests, sharpening rather than removing the question this page asks — what a physician does that a machine trained on the same textbooks still cannot.

What is the difference between a physician and a surgeon? A physician diagnoses and manages illness through examination, testing and medication, typically following a patient over months or years. A surgeon treats disease or injury by operating, usually for a single well-defined episode of care. Many physicians — internists, family doctors, cardiologists — never operate; some conditions are handled entirely by a physician, others are referred to a surgeon once medical treatment is exhausted.

How long does it take to become a physician? Most countries require roughly ten to eleven years after secondary school: four to six years of medical school followed by three or more years of residency in a specialty such as internal medicine, family medicine or pediatrics. The United Kingdom compresses medical school to five or six years but adds a two-year foundation programme before specialty training begins, so the total ends up similar.
