If I were you I'd make sure to get a second opinion Andrew.
It is kind of unethical for a doctor to tell you that you have cancer before the biopsy results are in, don't you think? It is unconscionable to have you this stressed out withOUT results!
That would worry me a LOT! I know everyone is praying for you to have a good outcome.
We have to advocate for ourselves. I know that I always get a second opinion because one just never knows what a new set of eyes may see.
If you don't like a doctor then don't go back. If a medical professional is cavalier with you? Step up to the plate for yourself! At the end of the day we are the only ones that know our bodies and what is really best.
