I had a call back and ultrasound after my first mammo, too. I have some milk ducts that are perpetually enlarged. I had to go back according to the protocol (every 6 months for 2 years, I think) to rule anything out. There was no change in their size.

Try not to worry. Easier said than done, I know.

I was quite happy with the mammo center with their promptness to get results back and to act quickly on follow-ups. I think I went back in the very next day, and the results were given to me in real time, if I recall. I wish every clinic operated like that.

Vibing for a good outcome,

Karen
