Hi Partovis - My husband had 4 recurrences. His SCCs were all very small, caught early, stage 1 or in situ, well differentiated, clean margins, neck disection found no cancer in lymph nodes, etc. so it was decided against radiation/chemo in all instances. His last check-up (including 2 biopsies) was good, so no real problems since he had laser clean-up of the lichenoids, lichen planus, leukoplakia in his mouth. He had no cancers on his tongue, no mets, and no HPV. He did lose 3 teeth in 2 different surgeries and his jaw bone was shaved - no cancer there either. In conclusion, he never had radiation/chemo. This is just OUR experience - your doctors are the ones who know your situation. Best of everything to you.
