Diagnosis for a recurrence is frustrating once so many years pass. I'm sorry your husband is having to revisit the same systems and scenarios he successfully managed in 2006.

The concept of a full glossectomy would be exceptionally tough to deal with. Particularly, after he has gotten used to the limitations resulting from a hemiglossectomy.

If he decides to not have the surgery. Your husband should consider how, as the tumor grows, his current functionality will most likely be adversely impacted. He will very likely end up dealing with the same issues as he would have with the total glossectomy.

There are no easy, absolute, clear choices.
