Chris, from all the research I did the message came out loud and clear not to use a PSA score as an accurate indicator of the level of cancer one might have. Indeed the first Urologist I consulted said all men are different and levels can vary enormously from one to another who might have similar conditions. 32 is significant but not that high in comparison to some men who can register in the hundreds.
Take heart that your mets and bone scans are coming out clear. If you start to distrust those then you're heading down a road of obsession that will not help your general outlook. As you've said, it looks good for you so go with that and once you're ready make your choice between the Sword or the Ray.
If you choose the latter feel free to PM me and I'll be happy to chat about my own experience in the North West.
Good Luck.
