Welcome Roger. Congratulations on making it through that hellish treatment. The tumor in my neck didn't go away all at once either. 3 months out from treatment it was still there though much smaller. 3 months after that it was gone. There are a lot of post radiation issues, most of which fade in time. Good luck to you on this continuing journey.
