Don't forget to tell him (don't ask) you want a copy of the pathology report asap=now in your hands. Then read it and tell others like herein what is written down, then you can try to make heads or tails of the actual results, not verbage the doc may or may not mention fully. Orally is not the same thing or memories are fairly bad after a little while, too. Copy of such and tests are always good to have and totally useful when seeking second opinions.
Hope the results are decent.
