[quote]Could a difference in the biopsy have made a difference on getting all the cancer out of my mothers jaw. Excuse me if this is a silly question[/quote]Not silly at all. I hope there is no recurrence. Either way I really encourage you to not look back other than to tease some learning for a future lesson.

Coulda-woulda-shoulda is a very slippery slope and what was is what is now. It becomes an endless game of second guessing and only causes unneeded stress and anxiety.

A surgical biopsy is a standard of care technique to establish the presence of cancer. So be glad now an accurate status will be determined.

The other common method is called a FNA (Fine Needle Aspiration), basically stick a needle into the suspected area and test the extracted material. My understanding is this is more prone to not finding cancer cells.

Best hopes for a clean report.
