Hi, I have had 4 biopsies on my Tongue in the last four years. I have Leukoplakia which appears to be Mild Dysplasia which keeps recurring. My oral surgeon told me, today. The best option is a more involved biopsy with an pathologist in the room looking at the samples util we get clean margins. it is my decision . He doesn�t know what he would do in my situation. Seems invasive, but I am worry I don�t want to ignore this. Looking for advice. From people who know more about this. The oral surgeon seems competent -- he said he is ok with either direction I choose (Frequent Follow up or more Surgery to get clear margins)

Anyone experience something like this in the early stages?
What type of doctor should i see, if not the Oral Surgeon?
Is this deeper biopsy really invasive?
I live in Southern Cal any advice on professionals is also appreciated.

I am 51, non smoker, lite drinker. Family history of other cancers.
