Bobby,
A biopsy doesn't have to be a surgical procedure.My dentist spotted a suspicious white spot on my tongue (after diagnosis and treatment)and I showed it to my surgeon at MD Anderson and he clipped a little piece of it with scissors and it was enough to biopsy it. A place as accesible as the inside of the mouth should be an easy spot from which to cut off a little skin for testing.
Best of luck,
Danny G.
