Which purpose is NOT included in the classification of surgical procedures?

In the classification of surgical procedures, the purpose of a surgery is often categorized into several distinct types, such as exploratory, cosmetic, and palliative. Each of these serves a specific function: exploratory surgeries involve investigating the cause of symptoms, cosmetic surgeries aim to enhance appearance, and palliative surgeries focus on relieving symptoms without curing the underlying disease.

Preventative surgeries, while they do exist and serve a purpose, are not typically included in the main classifications of surgical procedures that focus on treatment rather than intervention for future risks. As such, preventative procedures might include surgeries performed to prevent disease, such as a mastectomy for someone at high risk of breast cancer. However, they do not fit neatly into the traditional classifications used for categorizing the majority of surgeries according to their immediate goal, which is why this option is not considered a primary purpose within the standard classifications.
