Surgery is a medical specialty that involves performing operations on patients to treat diseases, injuries, or deformities. Surgeons use a variety of techniques, including cutting, suturing, and other methods, to perform procedures that can range from simple outpatient surgeries to complex procedures that require extensive recovery time. Surgery is often used to remove cancerous tumors, repair damaged organs or tissues, or correct structural abnormalities. It is a critical component of medical treatment and can have a profound impact on a patient's quality of life and health outcomes.
