At this point, we aren't totally sure. When his dr called with the biopsy results, they didn't think it required any amount of urgency but said they would discuss treating now if that's what my husband wanted to do. He goes along with what is being suggested (wait). We know they don't want to treat what's currently in the lungs and neck/head area unless they absolutely have no choice because both areas have each already had 2 rounds of radiation, and he's had 3 surgeries on the neck. Hence the "watch-and-wait" plan he's on. Now that it's moved into his bone, I have a new level of concern. That's why I'm curious to know if anyone else here has had this type of cancer spread to the bones.
