Welcome, @digger. Sorry to hear that the cancer has spread to your bones. I moved your question about asking if anyone had experience with Xofigo (radium 223) to this existing discussion:
- Radium223 (Xofigo) treatment for stage four prostate cancer https://connect.mayoclinic.org/discussion/radium223-treatment-for-stage-four-prostate-cancer/

I did this so you can connect with @norske46 who started radium 223 last year about this time. He can share his experiences with you and update on how things are going.

Digger, what chemo treatment did you stop? When will you start Xofigo?
