I would notify the surgeon of this, even though your biopsy is scheduled for Wed.
What is your question? It sounds like your doctor has been doing the right things, and biopsy appears to be the next logical step. Waiting for the biopsy and results is the hardest part, but a biopsy is the only way to know for sure what the mass is, especially since the mammo and US didn't help. Some doctors do MRI too, but with your mass growing quickly and becoming irregular, it seems you should just get to the biopsy right away. Hang in there, and be sure to ask what is the soonest you can expect your results. Good luck.
