Hi - I would say most people in our forum have received radiation and chemo treatments. It is extra artillery in this fight. My husband was one of the few who didn't have the treatment, just surgery, because, like you, his cancers (see my "signature" below - you can add one also) were all superficial (because they were caught so quickly), had clean margins, and were well differentiated, and his neck dissection pathology found no cancerous nodes. His have been in his cheek and on his gums, and one on his lip, all SCCs. He was never a smoker, no HPV (which they are finding in more cases of oral cancer now), but he does have leukoplakias and lichenoids. His doctor is monitoring him often, as lesions pop up every so often. This is just one person's experience. Others will tell you theirs also.
Now, without further adieu, welcome to the Oral Cancer Foundation forum! Where are you in Minnesota? Husband and I were born and raised in Winona and lived in the Twin Cities for many years after we were married.
If we can be of further help, please message us. Keep us all informed. : )
