Gel Bleed - Silicone Gel Breast Implant Risk
Silicone is made up of a sponge like mesh filled with silicone in oil form. It is known that some very small amounts of the oil part of the gel "bleeds" through the implant's shell. Although most of the silicone stays in the pocket, or is trapped in surrounding scar tissue. However, very small amounts of the silicone can possibly migrate to different areas of the body. It's important to remember that silicone has not been proven to cause cancer or other illness.
