Thanks for all the responses. I plan on talking to my doc about how I didn't appreciate the way she and her office handled things. I like her a lot otherwise.

I did go to Duke, and they determined that my lump was a "fatty necrosis"--benign. They gave me a "differential diagnosis" of DCIS or a fibroadenoma (benign tumor) on the calcifications.

Duke did the biopsy, and I am glad to say it was the benign tumor.

Duke also got everything done EARLIER than it would have been done here in my town, unlike what my doc predicted. Had I stayed here, I wouldn't even have had my biopsy until the 30th!
