Some diseases are best treated by direct intervention. A surgeon is a physician who has completed specialized training in operative treatment and who performs surgical procedures to diagnose, repair, or remove diseased or injured tissue.

Surgeons assess operative risk, obtain informed consent, perform the operation, and manage postoperative care. Subspecialties include general, orthopedic, neurosurgery, cardiovascular, and many others. Technical skill, decision-making under uncertainty, and team leadership are all required.

Modern surgery emphasizes minimally invasive approaches when appropriate, rigorous infection prevention, and enhanced recovery pathways. Outcomes depend on the surgeon, the team, the institution, and the patient’s condition. Continuous audit and morbidity review maintain standards.
