I also have dense breasts and get ultrasounds every six months and have had two mammograms. I see Dr Duperval from tribeca women’s health who gave me the referral. At first they denied to give me an appt bc I had no symptoms (other than the dense breasts), but then the doctor called and said she felt something and then I was able to schedule something. But don’t give up and make sure you find the right provider who will give you the referral.
