results normal after core biopsy

Today my family Dr informed me that my core biopsy  came back normal . My Bi rads was 5 prior to the biopsy . I'm still concerned that the biopsy may have missed the growth  seen previously on the Ultra sound. Could the radiologist have misclassified my ultra sound?  Or is it possible the  Radiologist who did the core biopsy  missed the place in question ? On the one hand I'm relieved yet on the other hand I'm concerned this may be a false negative result .

I doubt that a core biopsy would have "missed" the suspicious area but you might have your films read by another Radiologist if you have doubts. Biopsies are usually guided by some sort of imagery to locate the proper area.      Regards ....
