I'm with Gary on this one -- unfortunately, the notion of waiting until the "right time" to use radiation can turn out to be waiting until it's too late to be of any good use.

However, I also went back and reread your first post and noted that, as of that time, your husband was continuing to smoke and drink heavily, even after multiple recurrences. That's something that radiation won't cure, and if he really wants to get better, he needs to focus on that now.
