Current medical status: My aerolas are rough around the nipple. Just discovered them last week.
Current medical treatment: Putting lotion and cream on them does not help.

Given the data you provided, it is not possible to provide a direct answer whether the areola changes go towards malignancy or they are benign. The possible (though not conclusive) signs of breast cancer might be: lump, thickening, new/unusual pain, edema, warmth, redness changed skin colour, skin dimpling/puckering, itching/sensitivity/rush on areola/nipple area, nipple pointed inwards, nipple discharge, enlarged lymph nodes in the near areas, etc. It might be recommended to consult with your family doctor, who might want to perform a physical exam, do mammography (ultrasound, only if needed) and, depending on the results, maybe even a biopsy with pathohistological microscopic examination. These tests could prove the nature of your breast changes.
