With the changing trend of public aesthetics, more and more women are pursuing fuller breasts, and breast augmentation has naturally become one of the hottest plastic surgery procedures today. Today, I would like to talk to you about the 3 most common questions about breast augmentation with autologous fat. 1. Will fat transplantation lead to cancer? From the embryological point of view, fat and gland originate from two different embryonic layers. Malignant tumors that appear in the ectoderm to which glands belong can be collectively called cancer, while malignant tumors that appear in the mesoderm to which fat cells belong are called sarcoma. Liposarcoma of the breast is very rare, and no cases of liposarcoma following fat transfer for breast augmentation have been reported. In addition, it takes more than ten years for a typical cancer cell to develop into a mass, and unlike infectious diseases, the likelihood of a short-term illness is negligible. In other words, the claim that fat breast augmentation can cause cancer has no theoretical basis and is unscientific. When autologous fat is injected for breast augmentation, the fat is injected into the fatty area within the breast, so it has little effect on the mammary gland itself. So far, it cannot be proved that there is a direct relationship between autologous fat transplantation for breast augmentation and breast cancer, and there is no evidence that fat transplantation will increase the chances of breast cancer in patients. 2.I heard that calcification, hard lumps and necrosis may occur, is it okay? In autologous fat grafting, if the fat is not processed properly after extraction and there is too much fat, nodules will be formed because triglycerides will not be absorbed, or due to uneven injection, too many fat particles will be gathered at a certain point to form parcels, and hard nodules will also occur. Accidentally injected into the mammary gland is also prone to hard lumps and can easily cause breast disease, so hospital equipment and doctor’s skills are very important, you must look for a good doctor before surgery. As for necrosis, with the current technology and equipment, the probability of large necrotic nodules is very low, and only doctors who do not know how to operate this surgery will have this problem. However, even if the surgery is successful, the fat cannot be 100% viable, there will be a very small portion of the fat forming cysts and calcification, the percentage will not exceed 10%, and localized nodules and calcification below 10% will not cause any negative impact on health and body, so there is no need to be overly concerned. Once there is a large area of calcification, excessive vesicles must be surgically stripped and removed. 3.Can I do it if I have breast hyperplasia or family history of breast disease? Hyperplasia is not a tumor, so as long as it is not obvious hyperplasia can also be done, but if the patient is suffering from breast disease, or has a family history of breast cancer disease, the doctor does not recommend to do breast augmentation surgery with autologous fat. Finally, we are reminded that before breast augmentation surgery, we must do a detailed pre-operative examination to determine whether we are suitable. There are various means of testing, such as breast ultrasound, MRI or mammography, which is currently the preferred test for diagnosing breast diseases.
