Thank you for your responses. In my area it seems next to impossible to find a dentist who will do a complete exam which includes the Vizilite. One thing which stuck out to me about this light is that it wont differentiate between cancer and other more minor problems. That was what I was looking for, something that doesnt exist. I wanted this light to be able to tell if a sore was cancer or just a canker sore.

The reason behind this is that during my last visit with my ENT, he saw a sore starting right near where my oral cancer spot was. He said it was something to watch. A week later I saw my oral surgeon who mentioned the same thing. Maybe they dont realize what that means to a cancer patient, but to me it was very upsetting. So for now, since it hasnt healed I will sit tight till next month's ENT appointment then will insist it is checked.

Thanks again for your help.
