Before answering this question, let me start by noting that not all women are able to produce enough milk to breastfeed, regardless of whether or not they have undergone breast augmentation. As a result, those who have not attempted breastfeeding prior to surgery may not be aware that they were unable to do so beforehand, which is a key contributor to the misconception that implants negatively impact one’s ability to breastfeed.
With that caveat out of the way, the truth about breastfeeding after breast augmentation is this: When placed correctly by a board certified plastic surgeon who has extensive experience in breast augmentation, implants should have no bearing on your ability to breastfeed, as long as your body is able to produce a sufficient amount of breastmilk in the first place. Furthermore, in the rare event of a leak or break, the silicone or saline material inside breast implants should not pose a threat to any tissues or milk ducts inside the breasts.
Ultimately, if any of this is still a significant concern, there are specific techniques that can be employed to minimize any risk of milk gland disruption – such as submuscular implant placement and incisions made away from the areola – so be sure to ask your surgeon what would be best for you based on your future plans.
