Can you touch your chest to see if the contour of the prosthesis is still obvious? If the breasts on both sides are different in size, it is likely that the prosthesis is displaced or leaked. It's best to go to a local 3A hospital for a magnetic resonance examination to see the details of the prosthesis in the chest. Once the prosthesis is really abnormal, it needs to be removed as soon as possible. When the prosthesis is taken out, you can do autologous fat breast enhancement at the same time, and both of them can be done at the same time, so that the operation can recover well and you can have a full chest again.
