Numerous Pleomorphic Calcifications

I had my spot magnification done last week and now my report says that "there are several clusters seen. There is one with numerous pleomorphic calcifications. Malignancy cannot be ruled out. A biopsy of this cluster should be considered."
Also, I had an ultrasound yesterday for a suspicious nodule on the same breast. The radiologist came into the room to try and get a better picture of the ultrasound. He seemed to say that there was a cluster of what looked like cysts, but he wasn't sure what the cluster was. It wasn't clear from the ultrasound and again he suggested a biopsy. I will be getting that report in 2 days.
Aren't cysts liquid and therefore not suspicious? The radiologist said that cysts weren't necessarily liquid.
I am seeing the surgeon on March 10th as she is out of town. Should I be worried? Should I go ahead and schedule a biopsy? Is it okay to wait till March 10th or should I consult another doctor?
Thank you so much for your time. Any information on this will help.
