I didn't have a authorization when I went for mammogram had to wait until the doctor got into the office to ok it. Then the lady was sure looking for something. Used a ultrasound. She was doing it over and over again. Finally got a doctor to come look and she said the cyst was shrinking was behind the chip they had put in to mark the spot. That is good. Go back in another 6 months. I was there over 2 hours.
