Hello,. Since you are getting recurrent skin rash in the nipple area it can be due to fungal infection. You can take a curse of antifungals orally. Apply a thin layer of skin creams like clotrimazole( Mycelex) on the area affected. Such symptoms can also be caused by eczema, take non sedating antihistamines, fexofenadine (Allegra) to ease discomfort. Topical application of Elocon ointment on the area affected works well for nipple dermatitis or eczema. Avoid wearing synthetic fabrics, stay away from food allergy, animal dander, temperature changes, etc. Keep your skin moisturized and take care of your hygiene. Since you have a family history of breast cancer, you are suggested to get clinically examined by a Gynae/ GP to rule out Paget disease of the nipple or developing symptoms of breast cancer. This is to stay on the safer side. You will be treated accordingly. Take care. Hope I have answered your question. Let me know if I can assist you further.
