A medical operation, also known as a surgical procedure, is a treatment performed by a surgeon to diagnose, treat, or prevent a medical condition. This can involve cutting into the body to remove or repair tissues, organs, or structures. Operations can be planned in advance or performed as emergencies, depending on the patient's needs. Before a medical operation, patients typically undergo assessments to ensure they are fit for surgery. Anesthesia is often used to manage pain and keep patients comfortable during the procedure. After the operation, patients may require time to recover and follow-up care to monitor their healing process.
