I am having a slight milky watery plus sticky discharge from both the nipples while pressing them, was on antacid for few weeks, it started after that. It stopped in between but again the discharge is showing while I am on my periods. I am twenty five years old unmarried women. I have a breast cancer in my family history( my maternal aunt). Recently I feel my left breast to be very uncomfortable. Is it a symptom of breast cancer? Or is it normal.
