Are skin changes of the breast/nipple a sign of breast cancer?

Dimpling of the skin or retraction of the nipple may be a sign of an underlying breast cancer.  Some people are born with inverted nipples and this is not a problem.  But if a change occurs and the skin dimples or the nipple retracts you should seek medical attention to make sure that it is not a cancer.  Benign inflammation usually causes these symptoms but cancer must be ruled out.
