Hi jmc! Sorry I did not see your post until now. To give my opinion, yes, I would want a biopsy and copy of the records. A biopsy is the only 100% way to know. If it is nothing, then you can have peace of mind. If not, them catching it sooner is always better. 80% of lumps are benign so the odds are in your favor, and sometimes microcalcifications can be hiding a lump. If I were you I would insist on a biopsy. Please let us know how it goes at the doctors today, we care!
It's only when we truly know and understand that we have a limited time on earth -- and that we have no way of knowing when our time is up, we will then begin to live each day to the fullest, as if it was the only one we had.
