question: white spots on both sides of your mouth? That would be somewhat encouraging, since it would be doubtful that cancer would occur in both places simultaneously.

You need to look in there with several mirrors and note what it looks like for yourself. And then look every day to see if it gets better or worse. If it gets better, that will be good news. If it just sits there, or gets larger, then that's not such good news, but it still might have an explanation other than cancer. The only way to know is to go to see an ENT and let him/her get an early look.

I use an old-fashioned cheap shaving mirror...on a wire stand, with a mag. side and a reg. side...I place that on the table. I have a small, bright flashlight, and another small rectangular mirror (a purse=sized makeup mirror) I hold the light in one hand, and the small mirror in the other, and I get a really good look in the magnifying mirror. Let your wife (?) look too, so you'll have another set of eyes at work, and so that she will be involved from the beginning.
