Breast augmentation, also known as breast enlargement or breast augmentation, is a surgery to improve the female body shape and restore the unique curvature of women by implanting medical materials or transplanting their own fat tissues, so as to increase the volume of the breasts and make their shape fuller and more proportional. Breasts are an important feature of female physical beauty. For those who have the need for breast augmentation, as long as they choose a regular hospital and a professional surgeon to perform the surgery, the risks of the surgery will be greatly reduced and the desire to improve the shape of their breasts will be realized. The risk of breast augmentation is related to the type of surgery chosen for breast augmentation. The common types of breast augmentation include breast implant and breast augmentation with autologous fat. Breast implants need to be placed in the body through surgical incisions, and the recovery time is relatively long. In addition, regular review is needed after the implant surgery to prevent side effects such as postoperative infection, implant exposure, and implant rupture. After breast augmentation with autologous fat grafting, side effects such as fat liquefaction, nodules, and asymmetry between the two breasts may occur. In addition, the final result may need to go through 2-3 filler surgeries to achieve, each with an interval of at least 3 months. The result will also be limited by the amount of excess fat in other parts of the body, and those who are too thin are not suitable for breast augmentation with autologous fat.
