Surgery (gr: cheirourgia da χείρ, χειρός, hand and 人ργον, work) etymologically means a manual work activity. In fact, it is the science that deals with studying those diseases that by being able to cure with the hands, are, as said, surgical. Considered a branch of the medical sciences, it actually has equal dignity, as evidenced by the history of its evolution, the contrasting opinions and diversified paths with respect to medicine over many centuries and the definitive reunification in a common university course that confers a degree in Medicine and Surgery. It deals with various aspects (aetiology, diagnosis, therapy) of all the diseases pertaining to it and is therefore called General Surgery.

The imperfections that cosmetic medicine deals with may be congenital or may be acquired over the years, for example due to ageing or lifestyle.
