Prostate cancer glesion score 7, and psa 7.25, how likely would it have spread to bone? did radiation, now psa 0.50. my bone sore 2 yrs later now

Very unlikely: It would be unlikely to recur but some patients(10-15% can relapse in 5-10 years). So annual monitoring is advised.

Unlikely: Bone cancer is rare in patients with psas under 20. As a mentor of mine once said, though "the good thing about cancer is that it gets worse." what he meant was that if you have had bony pain for a while and if it has not been getting worse, then it is unlikely to be cancer.
