Medical breast enlargement for underdeveloped breasts is commonly known as augmentation mammaplasty. The female breast is not only a functional organ, which has the role of nurturing life, but also a physical organ, which is the most prominent symbol of female physical beauty. A full breast is a symbol of female charm. Women’s pursuit of breast beauty is one of their nature. So the pursuit of breast augmentation is also normal. There are many ways of breast augmentation, and the common fillers include Omnidene, silicone gel implants, and autologous fat. More than a decade ago with the use of breast augmentation with injections of Omnidene, a boom was created in the world of beauty institutions, but in subsequent studies it was found to have carcinogenic effects, so it was gradually eliminated. Currently, the main materials used for breast augmentation are silicone gel implants and autologous fat grafting. Silicone gel implants have a disc-like appearance, are soft to the touch, and have a low rejection rate. Plastic surgeons mainly place them behind the pectoralis major muscle, and generally the implants can last for more than ten years, with the option of replacing them after more than ten years. As long as there are no complications after the early implantation, the later period is relatively safe. And the prosthesis has no abnormality to the human body itself, will not cause cancer, and is an absolutely safe product. Autologous fat injection is done by suctioning fat from the legs, abdomen, back and other parts of the body, and then injecting it into the breasts after centrifugal filtration and other treatments. The main advantage of autologous fat is that there is no rejection and it comes from our own tissues, but after surgery, it can also lead to liquefaction, necrosis, calcification and other adverse reactions, but the advantages are permanent presence, natural appearance and good handfeel. In conclusion, whether it is silicone gel breast implants or autologous fat transfer breast augmentation, it will not have any effect on human health, so women who are interested in beauty can try it with confidence.
