In Castration resistance the can PSA drop 2 points in a month? What is the treatment at castration stage?
You need to contact a Cancer Center Treatment of America ASAP. They do NOT charge for consultation. If those numbers you posted are correct I would be on the phone NOW! There are a few locations around the U.S.
For proper imaging that can shed light on any metastasis, I suggest your father finds a good teaching hospital where he can undergo a PSMA PET CT scan. This will clearly show if there is metastatsis on the bones and if so, the extent of it.
A regular “bone scan” is not as good a diagnostic tool.
Good luck!
