Tina, There's a lot of things it could be and not be cancer. A couple of months ago my oncologist insisted I have an area on my cheek biopsied, from the pics on the site here it was a tossup whether or not cancer. Had the surgeon take the whole lesion out, about the size of a dime.

Turned out to be lichen planus, really nothing to worry about. But, better safe than sorry, and instead of having a pretty bad looking lesion, it's now just scar tissue.

Hang in there and good luck.
Bob
