I think you are right to get a second opinion. It is probably ok, but if not you need to know. If the doctor wants to biopsy the area, do it. That is the ONLY way to know 100%. At least then you can relax or start on what is needed.
Let us kno how it goes ok? Hang in there!
It's only when we truly know and understand that we have a limited time on earth -- and that we have no way of knowing when our time is up, we will then begin to live each day to the fullest, as if it was the only one we had.
