Breast augmentation is a common procedure, and these days silicone implants have become the implant of choice for many patients. One of the most common questions I get to hear from my patients is if silicone breast implants can have a negative effect on a baby. It has been suggested that children born to, and breastfed by mothers with silicone breast implants might be adversely affected by transmammary or transplacental delivery of silicone during either breastfeeding or pregnancy.
What about silicone diffusing through the milk ducts and entering the breast milk? The current evidence does not support diffusion or transport of silicone gel across membranes that will lead to silicone in the breast milk.
Silicone is an inert material. It is commonly found in many different products, and it does not create abnormal reactions if it is inserted into the body. Multiple research and studies show that it is safe to use for cosmetic surgeries. There is little evidence of any elevation of blood or serum silicon or silicone concentrations in women with silicone breast implants. I am not aware of any studies of reproductive or teratologic effects of silicone in humans.
Yes, some patients might develop capsular contracture, and yes, the body will always create a scar around the implant, but that is about it; the silicone itself is not toxic. It is well known that silicone molecules can cross the membrane of the silicone implant.
Today, the implants are more cohesive and there is less silicone bleed, minimizing complications. Nevertheless, if you are pregnant, you need to recognize that your breasts are going to change and you might need additional surgeries in the future to replace the implants or lift the breasts, among other things. Pregnancy can affect the shape of your breasts, but the implants will not affect the baby.
