Mammaplasty (also called mammoplasty or mastoplasty) refers to a group of surgical procedures, the goal of which is to reshape or otherwise modify the appearance of the breast. There are two main types of mammoplasty:

1. Augmentation mammoplasty is commonly performed to increase the size, change the shape, and/or alter the texture of the breasts. This usually involves the surgical implantation of breast implant devices.
2. Reduction mammoplasty is commonly performed to reduce the size, change the shape, and/or alter the texture of the breasts. This involves the removal of breast tissue.
