Sharon, there's no telling if the itchiness is related to the surgery, or to some other issue. I'd be concerned enough to go back to the doctor and find out what's causing this. A rare form of breast cancer, Paget's Disease, can begin with what appears to be eczema around the nipple: redness, scaling, flakiness, and itching. If those symptoms don't respond to a typical eczema treatment (I assume that's what the antibiotics were supposed to treat), then you need to delve further into what might be causing this. So I'd call the doctor, tell him/her the treatment didn't work, and that you'd like a referral to a breast specialist to find out what's causing both the nipple irritation, and the inversion.

The two might be totally unrelated; and chances are, none of this has anything to do with cancer, especially at your age, and given the rarity of Paget's. Still, you need to rule it out - so ask to see a breast specialist, OK? And don't take "no" for an answer; too many doctors want you to just "wait and see." In my opinion, if the suggested treatment doesn't solve the problem, why wait? Find out what the issue is, and deal with it. Good luck - PJH
