Recent worldwide media speculation that silicone gel-filled breast imp
lants may be linked to an increased incidence of breast and other canc
ers, and connective tissue disease (particularly systemic sclerosis) h

these implants, the US Food and Drug Administration has restricted the
ir use to research and breast reconstruction. Research has so far fail
ed to prove a causative relationship between silicone implants and can
cer or connective tissue disorders.
