Mark, want to back up David on the advice to make sure you need that follow up surgery on the node before getting it. Our cancers are similar - BOT and node. My first doc wanted to do a neck dissection, second opinion doc said studies showed 80 percent of the nodes being removed after treatment were no longer cancerous after chemo and rads. For this reason they changed their practice to waiting a few months after treatment and then rechecking with a PET scan before doing follow up surgery. I'm closing in on five years and so far so good.
