"Worth it" is a complicated decision you have to make after long discussions with your care team, but I have read that an increasing number of oncologists believe in adding early chemo when there are too many metastases (bone or otherwise) to treat individually with external radiation. It probably varies from patient to patient, including other factors like age and general health, but it seems like it's a real option. I wish you the best while you talk and mull it over.

I'm not sure what "is it worth it" means. Can mean different things to each of us. I have stage 4 metastasized to the bones, top to bottom. Chemo and Firmagon were my first treatments. I didn't pick that option, I was still stunned that I had the problem. I will say that it made my pain go away and that it has been 15 months since diagnosis. I had 10 rounds of chemo and as doc said, I'm finished with that for now. For me it was worth it, without it I would be in a bad place. Last scans in june showed it wasn't spreading. Best to you on your journey.
