Dysplasia is concerning...are they asking you to followup in a few months? If not, YOU must follow this up. It is pre-cancerous, it is abnormal cells. Not necessarily going to be cancer, but not normal cells. So someone needs to keep a close eye on it. You do not need to spend every day thinking about cancer, but you need to dilligently follow up. If, you are still not content see another oral surgeon, or go to a big center and see what they tell you to do. Like Brian says, if a lil' nerve medicine can take the edge off of your worries take it, it may allow you to think easier about what you need to be doing. Just make sure you followup always re; this biopsy results.
