I have been diagnosed with this 2 times now. The first surgery was two years ago. biopsy showed Moderate Dysplasia Epithical Hyperkertosis. In May of this year I went in for the second time, biopsy showed Mild at this follow up he gave me a gel to put on my tounge 2 x day to help the healing. I went in for another follow up and he tells me at this time that my test showed cancer cells beyond the perimiters of the biopsy WHAT?? and I still have a small white spot. I don't understand why they didn't take all if it out. Now I go back in June 27th for Laser. I don't know what to think. I have stopped smoking I hope this works.
