Scar tissue, called "capsule" is formed around every breast implant. If this tissue overdevelops and contracts, the breast may harden and sometimes get a balloon-like appearance. This is called "capsular contracture". It usually requires surgical treatment. The incision is reopened, the implant is removed together with the capsule, and finally the implant is reinserted. Sometimes this treatment is effective, but unfortunately the contracture may recur.
