Plastic surgery has a long history dating back to ancient India and Egypt. Modern plastic surgery techniques were developed in the early 20th century, especially during World War I to treat facial injuries. The most common plastic surgery procedures in the UK are breast augmentation for women and rhinoplasty for both men and women. While plastic surgery is less common in the UK compared to other countries, demand has been growing in recent years, especially for procedures to correct gynecomastia in men. Australia has also seen growth in plastic surgery, with a study finding that women who have had cosmetic procedures were more likely to frequently use other health services as well.
