Breast augmentation surgery implants are usually silicone implants, which are safe to handle and longer lasting. The lifespan of a conventional implant is usually about 15 years, after which the strength of the silicone gel decreases and there is a risk of rupture when pressure is applied. If a rupture is detected, the candidate will need to have the prosthesis removed in a timely manner and a new one implanted, which can usually be accomplished with a simple minor surgery. Alternatively, if the candidate is older and feels uncomfortable and unsafe with the implants in their body, they can have them surgically removed, but at the same time the results of the breast augmentation will no longer be there. If autologous fat is used for breast augmentation, there is usually no rejection reaction and it is safer. Candidates need to have regular medical checkups, and if no other problems are found, they can usually be left alone. If calcification is found in the breasts and symptoms such as hardness, swelling and pain occur, the calcified spots or the implanted part of the fat need to be removed. This usually occurs early after autologous fat breast augmentation.
