I went for about a year with an ulcer on my tongue. I wore night guards and it never got better and finally my dentist (whom I worked for at the time) said "Suz, I think this needs to be biopsied" and off I went. At that time I never thought biopsy meant we were checking for cancer. I realize now that was dentists' fear but I didn't know it then.
So...here I am 3 years later:) Just so happy I finally found this site!
