@4rs I am curious what your reason is for the preference of proton therapy? Any chance of mentioning what your insurance carrier is?

My pet scan is tomorrow, oncologist is the next day (at Mayo Rochester). So far everything points to no spread outside the prostate. I have multiple prior surgeries that make surgical options higher risk, so I'm leaning toward radiation therapy but worried insurance won't cover proton therapy.

I'm still in the self-research stage as I haven't seen the oncologist yet. I understand that the accuracy of the proton beam appears to make it the best option if cancer is contained, but I would think the lack of focus of photon radiation could be a benefit to catch any nearby cancer if it has started to spread out of the prostate. But then again, I'm also worried that proton won't be approved by my insurance so may just be trying to rationalize accepting a different treatment.
