I have dermatitis on my breasts and had all the affected skin removed from one of them for testing to rule out cancer. After my scar healed, within just a few days the dermatitis or rash came back and is now worse than what it was to begin with. If all the affected skin is removed, how quickly can the skin develop into dermatitis or a rash? I am still concerned that it is not dermatitis but rather Pagets Disease of the Nipple and that even though a biopsy was done, it was listed as a reoccuring rash and that maybe the lab did not test the sample for cancer cells. My breasts are the only location on my body that has this rash and I have never had problems with dermatitis any where on my body. The rash developed over a year ago and I was using a steriod cream to prevent it from forming, but if I do not use the cream every day, the rash develops very quickly. What do you think my next step should be?
