A retracted or inverted nipple is one that doesn't stick out or protrude past the level of the surrounding skin. If the nipple has always been this way, there is no cause for concern -- it's normal. If a nipple that used to protrude now is retracted, the finding could be a sign of a mass or tumor in the breast.
