I have had a fair number of women with silicone implants pass through
our clinic, but the incidence has decreased significantly over the
past few years.  The women had no more problems than anyone else.  But
you also have to realize that silicone implants are done in two ways.
Either with a periareolar incision, which results in poor milk
production and possibly other problems such as pain, or with an
incision done posteriorly and inferiorly on the breast near the chest
wall, with no real problems, except concern by the mother.  In
Toronto, breast augmentation is almost always done with the second
type of incision, but if you are somewhere where the periareolar
incision is done, you may find a whole lot of different problems.

In all the babies (about 2/month in the heyday of implants) I have
seen nursing from mothers with silicone implants, not one had any
symptoms which could be attributed to scleroderma like lesions in the
esophagus.
