Hi, Maam,as you are a hysterectomised patient,did you take hormone replacement therapy or are you still on HRT? HRT in the long run can be a cause for breast cancer. Thickening of subcutaneous tissue around the nipple area which is tender can be due to Areolar tissue infection, mastitis, malignancy. You need to do a mammography,usg of the breast and a complete blood count along with a proper clinical evaluation which has to be performed by a general surgeon. Meanwhile,have some antibiotics like cefixime and anti-inflammatory like aceclofenac and serratiopeptidase tablets for symptomatic relief. Hope your query is solved. Take care
