What is breast enlargement or breast augmentation surgery?

Breast augmentation or enlargement surgery is an operation in which the breasts are made bigger by the addition of mammary implants. The implants may be saline or silicone. The implant is also known as a mammary prosthesis. It typically takes from one half hour to one and a half hours to place the breast device, depending on such things as pocket location, incision, and the type of implant used.
