To ultrasound or not to ultrasound? my first mammo was bi rad 1 my second was bi rad 2 and said calcification. ins wont pay but i can self refer.

No: Birad 1 and 2 are a watch only. If you are concerned another ultrasound won't help. See a surgeon.

No : Birad 1 is a normal mammo, birad 2 means benign finding. There are many benign findings , including some types of calcification, which a radiologist may or may not mention in the report at their own discretion. If they choose to report a benign finding,they must call mammo B2. If not, it is B1. So 2 mammos can be identical, and one is B1, and the other B2, depending only on report structure.
