[quote=Caroline1972]I have a question, let's say it is something but the pathology shows she got it all and the margins are clear. Is that the end, like with a basal cell carcinoma or does he still need to go through treatment? [/quote]
Short answer: It depends.

In my husband's case (see my signature), what had initially been diagnosed as dysplasia (abnormal cells, but not cancer) did turn out to be squamous cell carcinoma when the whole white patch was taken out -- but it was removed at such an early stage, and with clear margins, that the cancer specialist ENT he saw after he got the SCC diagnosis said no further treatment was necessary. That said, he did go back to that ENT for checkups on a regular basis; the appointments lengthened out over time, and now he gets checked annually. (His dentist also checks him with a VELscope and refers him to an oral surgeon whenever she sees anything out of the ordinary; no problems so far, knock on wood.)

Others here have had clear margins, but because of concerns about possible spread, or the size of the tumor, or nerve involvement, or the staging that was determined from the biopsy and other tests, they've gone through radiation/chemo.

Here's hoping you don't have to be concerned about any of this -- but if it turns out that you do, you're in the right place for information and advice.
