Hi staceyanne
Its capsule contracture. At the time of the initial surgery, a pocket is made for the implant. During the healing process, a capsule forms which your body then starts to shrink. Under normal conditions, the pocket remains open, thus allowing the implant to look and feel natural. However, in some people, the capsule will tighten, and squeeze the implant. This makes the breast implant feel hard, and distorts the appearance of the breast. In the later stages, the implant feels very firm, and may take on a “ball-like” look. It is important to remember that it is not the implant that has hardened. The shrinking of the capsule compresses the implant, causing it to feel firm/hard. Xx
