Breast augmentation is the enlargement of the existing breast volume by placing a prosthesis under the breast tissue. During the breast augmentation process, the recovery of the breast tissue should be performed simultaneously against sagging and looseness, if any. In Which Situations Is Breast Augmentation Surgery Performed? Breast augmentation surgery is most often performed to increase breast size in women who are not satisfied with their breast size. Apart from this, breast augmentation surgery can be performed for different reasons. Breast augmentation surgery can be performed to support the recovery of sagging and loosing breasts after breastfeeding or serious weight loss. Breast augmentation surgery can be performed to provide breast volume to women whose breast structure has not developed due to chest wall anomaly. In addition to these situations, breast augmentation surgeries with prosthesis can be performed to create breasts during the sex change process.
