Abstract: A system and method for augmenting a woman's breasts is claimed. The system includes two separate breast prostheses that are used to enhance each single breast. A first breast prosthesis is surgically implanted under the pectoral muscle behind the breast. The first breast prothesis augments the posterior section of the breast nearest the chest. A second breast prosthesis is provided that is surgically implanted between the breast tissue and the pectoral muscle. The second breast prosthesis augments the anterior section of the breast in front of the pectoral muscle. The second breast prosthesis provides the breast with a large size and soft texture, while the first breast prosthesis helps blend the augmented breast into the chest for a more natural appearance.
