[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  You have history of tobacco chewing for long time.  You may have subbed mucosal fibrosis or squamous cell carcinoma or just hyperkeratosis.  Furthermore, you should go for biopsy diagnosis.  It will give you exact idea regarding cause. Then you should take treatment accordingly.  For biopsy, you should consult general surgeon.  Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
