Hi! Gone through your query. Please make sure you QUIT tobacco immediately. This can be a precancerous lesion. In most cases of prolonged smoking, it is leukoplakia. You did not mention if there is burning sensation or any pain etc. Get your biopsy done with your oral surgeon. You must be on a healthy lifestyle, quit tobacco and alcohol. It can be cleared usually in few months time. Hope this helps.
