COMMENT- THOUGH THERE IS NO EVIDENCE OF FRANK INVASION INE THE SUBMITTED TISSUES IT IS SUGGESTED THAT THE ENTIRE LESION BE EXCISED AND EXAMINED TO RULE OUT MALIGNANCY. EXPLAIN REASONS AND TREATMENT TO BE TAKEN

you need to talk to your dentist and have him explain it all to you. did he not when he examined you? well, he is definatly taking your case seriously and ordering good labs, but you need to tell him he needs to break it down and explain it all a little more clearly to you. this write up says to me that he needs to rule out any possible cancer, and that you do seem to have some issues steming from your dysplasia. hopefully dr. sam will come in here, lol, i haven't been in school for that long, lol! i understand the terms, but i do not want to jump to conclusions as to what your dentist is saying. but yes, your doctor did write up that your dysplasia is severe (4th line from the bottom). I'm not sure exactly what your question for us was, but i hope i helped. good luck and avoid acidic foods and drinks and alcohol and tobbaco :o)
