Sorry for your troubles. I had 5 recurrences, so I know how it is. I would rather not wait. Even if your husband decides to start treatment now, It may take a week or two to begin. Waiting 8-10 weeks more, to see how it's behaving, which is already confirmed metastases, may grow, and may take several more weeks to start. It's usually best to get any cancer early. Has anyone considered cyberknife, surgery, introperative radiation treatment? And what kind of chemo or targeted therapy is being considered. Maybe get a third opinion, but this will take time too. Good luck.
