Will my Breast Implants Block Milk Ducts?

It is not the implants that can block your ducts but the location of the incision in the areolar. By incising that area there is a potential of damaging the ductules, especially in smaller areolae. 

Implants are placed behind the breast tissue and do not interfere with breast feeding at all.  In some rare cases, if the implants are placed through an incision around the nipple, some milk ducts may have been cut during surgery.  However, even in that situation, breast feeding is possible since most of your milk ducts should still be intact.
