I'm really concerned for you and this doctor. He doesn't know what it is, but it's not cancer??? That's silly talk. All over this forum you will see that you need a biopsy to know what it is. He should want to do a biopsy to know what it is.

My spot looked like it was nothing too. Just a canker sore looking thing that wasn't going away. I went a whole year before I had a biopsy and I am thankful every day that it was caught before it was much worse.

I hope someone will be able to give you some answers.
