Thank you Brian and Christine for your concern!
I had the biopsy this Tuesday, the results will come out next Friday, so slow. The surgeon said it was not cancer, but he didn't know what it was and recommended the biopsy.
However, it's been four days after the biopsy, my lower lip still feels numb and a little swelling. Also, the wound on the site with the suture inside my mouth now has expanded and hardened, and more ulceration. And there is a big hole also. Is this a normal reaction after biopsy? Is it possible that the biopsy stimulate the growth of tumor?
