Thanks...I will suggest that to him. Forgot to mention in my original post...the tumor in his lung has not grown since he started treatment but it hasn't shrunk. And...two additional spots showed up that they think is metastatic. And a lymph node showed possible mets as well.
(Cindy -Glad you're doing so well. I was dx'd with breast cancer 3 yrs. ago...all done w/treatment...and in remission.)
