It's possible, if not enough tissue sample was taken from the suspicious area or from the wrong area of a lesion during the biopsy, probably done in the office like scalpel, punch biopsy or FNAB. Your doctor is just reserving his opinion until further studies are done under anesthesia, and checking the other structures to be sure or not. Good luck with the biopsy. Try to relax, keep busy until then, which is easier said then done.
