Took awhile but we have diagnosis

Just sharing where we are from starting in Sept 2022 with OH with a of PSA 290.  Bone scan clear (phew) CT scan T3b with some lymph node and seminal vesicles involvement.  OH put onto lifetime palliative hormone treatment straightaway (6 monthly injections), just a few hot flushes so far.  OH quite calm in the process while needing to wait for a clear diagnosis which seemed to take so long but I felt relief when the HT started.  Finally a prostate biopsis was done January 2023 which came in at G5+4 = G9.  Diagnosis appointment January 2023 resulted in outcome of locally advanced cancer and next will be oncologist appointment (which is not yet in place).  I worry about the high PSA for just locally advanced PCa but maybe the G5+4 is the reason. Suggesting RT as next option.  So we are T3b N1 M0 and G5+4 with final PSA 264, OH aged 77.  Lucky to have got to that age before symptoms came but we still have some questions.  CT scan didn't suggest anything apart from lymph node involvement apart from possible renal cell carcinoma (hoping talk with oncologist will explain that) but when symptoms started OH also had ongoing consitpation - thinking pressure of enlarged prostate on bowel etc.  I did worry that such a high PSA meant things were worse than T3b but fingers crossed maybe not.  A big thank you for all your posts I have been reading since Sept.  They have really helped me.  I have only just joined to share where we are and to engage more.
