Breast augmentation, technically known as augmentation mammoplasty, is a surgical procedure aimed at improving the size and shape of the breasts. In this plastic surgery, a silicone implant is placed to generate the changes desired by the patient. Depending on the patient’s characteristics, it can be placed behind the mammary gland or behind the pectoral muscle (the latter being more painful). The scar is usually located at the lower edge of the areola.
