How safe are Silicone implants?

Whatever the filling of the implant, the outer layer is made of silicone.
Silicon is a naturally occuring element which becomes silicone when it is
combined with carbon hydrogen and oxygen. Silicone is manufactured into
many items including cosmetics, foods and medical implants.

Many studies have been conducted to establish whether silicone breast implants cause certain diseases. As a result of these studies we can say that at present there is no evidence to suggest that silicone breast implants are associated with an increased incidence of breast cancer. There is also no evidence to suggest that these implants cause autoimmune diseases such as rheumatoid arthritis.
