Ben, I was told by my dentist for months, the sore on my tongue could not be cancer. I was even sent to an oral surgeon who biopsied it and said it was not cancer....finally, finally, I was sent to another oral surgeon in May (this all started around December,probably had it longer) and he took ONE look at it and told me it was SCC.....I guess I wanted to believe my dentist so I kept taking antibiotics and hoping it was a tooth rubbing my tongue, should have gone to an ENT please get checked by someone else.....Carol
