Sammie,
How do they know the nodes are clear? Did they do a neck dissection? Heather's surgical margins were also clear. She did have it in 4 nodes, but there was no perineural involvement, no extracapsular spread and her tumor was well-differentiated, which were all supposedly good signs that the cancer had not spread beyond the nodes.
She had aggressive surgery in Sept, started RAD in Oct, had a recurrence in March and died in October. I'm not saying this to scare you....well, yes I guess I am in a way. You need to be scared enough to seek a second opinion. Base of tongue SCC is about as bad as it gets. You want to attack this with everything you can in the first go-round, because you don't usually get a second chance.
If Richard had a neck dissection, I wouldn't worry as much. But if he didn't, how can the doctor say the nodes are clean? Be aware, be proactive and get that second opinion.
