Difference Between Surgery and Operation
When people hear the words surgery and operation, they often assume both mean the same thing. While they are closely related, there is a subtle yet important difference between surgery and operation in medical language.
In this article, we explain the meaning of surgery, the meaning of operation, how they differ, their types, and when each term is used in simple words.
What Is Surgery? (Surgery Meaning)
Surgery is the medical field or discipline that treats diseases, injuries, or deformities by physical intervention on the body.
In simple terms:
Surgery is the branch of medicine that deals with performing medical procedures.
It includes:
Diagnosis
Treatment
Repair of body tissues

What Is an Operation?
An operation is the actual medical procedure performed on a patient.
In simple words:
An operation is the action that happens during surgery.
It is the hands-on procedure done in the operating room.
Example:
