Hello, proliferation. This is a complication after prosthesis implantation. It is tissue hyperplasia caused by the immune function of body tissue to prosthesis. . Nothing, just a little more. . . If you feel that it affects the appearance, you can remove the hyperplastic tissue by surgery. However, I still want to tell you that it is possible to continue to grow after this resection. After all, there are foreign bodies in the prosthesis, which will stimulate proliferation in unison.
