Hello Fozz, sorry you have to be here.
I will take a stab at this so first things first. I would consider getting a second opinion on the biopsy pathology to be sure of exactly what was reported. Johns Hopkins is well known for this service but other respected pathology groups can perform this also.
https://pathology.jhu.edu/patient-care/second-opinionsWould also suggest getting an opinion from a NIH designated cancer center.
https://www.cancer.gov/research/infrastructure/cancer-centers/findMRI and Biopsy Discrepancies - Everything possible has happened. I started with a G7(4+3) from biopsy and ended up at G9(4+5) after surgery. Some men have had a number of negative biopsies before finally finding a small tumor with high risk G9 pathology.
PET Scan Insights - PSMA PET scan may or may not find out more. The PSMA PET scan is like the MRI in some ways in that it can not determine a Gleason score, only microscopic analysis of the cells can do that.
Decision Between Surgery and Radiation - These decisions become quite personal and you will have no end of radiation recommendations for a myriad of methods. Get the PET scan and second opinions done then wade into that decision. The urologist will recommend surgery as that is what he/she does. The radiation oncologist will recommend RT, duh! A decision for another day.
Experiences with Prostatitis and Cancer Together: No comment, never had together.
TRT and PSA Levels: No experience
Encouragement or Advice: Define favorable, treatment will probably be successful and you will die from something else. G7(4+3) means treatment is not optional but leaves most options available to you.
My concise signature highlights my journey. 72 now and the details are just a nightmare I prefer to forget about
which the six month PSA testing reminds me of.
