 [ Symptoms ] i am 60 years old on my left breast the nipple is sensitive when something rubs against it what can i do [ Disease ] assuming your mammograms have always been clear and your nipple is not leaking any fluid this sensitivity may simply be due to dry skin if you have not already tried applying moisturizer to the nipple i would suggest you do that you also may try padding the nipple inside your bra with a piece of soft gauze to see if that helps if the sensitivity persists or if the nipple gets red or crusty looking i would suggest you see your primary health care provider it is possible for cancers to arise in the nipple this is called paget is disease of the nipple  though it is not very common hope this helps
