I don't know what causes it, but I do know of a product available to healthy women (no hx breast cancer) non-surgical, that promotes breast growth. I have a client who used this after involution when she was dismayed that her breasts had "deflated" and was very pleased with results. www.brava.com I have no financial interest in this product....just wondering what you all think. I am also interested in learning what others think of the nipplette device to correct inversion, before pg/lactation. I wonder that it might be painful, just as bf is often painful for women who present with inverted nipples, but I wonder if some of the breast/nipple presentations that make latch/supply so difficult, like breast hypoplasia, might be corrected non surgically prior to pg..... wouldn't that be something....
