Should I stop breast feeding if my silicone implant has ruptured?

I have never heard of a ruptured implant causing nipple/areola numbness or change in color. I do not feel these are related to your breast impalnts
First, with a change in the breast appearance, you should go to your implanting surgeon and have a physical exam and request an MRI which will diagnose if the silicone implants are intact.

To answer these questions, we must first examine the different types of implants and how they affect nursing. The primary concern about breastfeeding with implants is the potential for them to burst and leak into breast milk. If saline implants leak into the milk supply it’s no great cause for alarm, the leakage won’t hurt the baby or the mother.Silicone implants, on the other hand, are notably more dangerous because they’re made of plastic. However, even cow’s milk has a certain degree of silicone in it. Nevertheless, the chances of implants tainting breast milk are slim.
