After breast augmentation, many women worry that if they have implants which contain silicone, either in the envelope or the gel, they may have silicone in their breast milk. Studies have not shown this to be issue of significant concern. In fact the amount of silicon in the milk of women during lactation, with and without breast implants appears to be the same. As a side issue cow's milk contains far more silicon than breast milk. Whether or not this is important remains to be discovered.
Recent studies have NOT confirmed any relationship between breast implants and congential abnormalities or other problems in children born to women who have implants.
Women who have had breast enlargement are usually able to lactate and breast-feed in the normal way, unless sensation has been disturbed. Some women cannot breast-feed even if they have had breast surgery. Some surgeons discourage an incision around the nipple in women who have not breast fed or completed their family. These surgeons worry that an incision around the nipple is more likely to reduce sensation in the nipple and therefore make breast feeding more difficult.
