Breast Augmentation Surgery with Fat Injection Breast augmentation surgery with fat injection is one of the breast augmentation surgery methods. People are looking into alternative methods because of the information rumouring around the internet. Breast augmentation surgery with fat injection is conducted by taking the fats from an unwanted area and injecting them into the breasts. It is conducted under clinical conditions. The taken fat tissue which is injected under the breast tissue melts after 12 months. The process has to be renewed when the melting starts. There might be a breast size difference in the left and right breast caused by different melting speeds. This difference causes inequality. The breasts become asymmetrical. In this method, certain information about how much your breasts are going to be augmented can’t be given since firstly the fat amount that can be ejected from the patients body has to be determined.
