I did think of starting a new thread, with a new title. Looks like I have moved into another phase. The results of the PSMA scan show spread to a number of lymph nodes right up to the neck. SABR is not on offer. An "off piste" choice is lutetium 177, but that would require approval from a specialist and my insurance company.
Aabiraterone and prednisone are the other option. I have said I need time to think, so seeing the oncologist in January.
Thanks Chris
