@muhammadali1951 The PSMA PET scan will provide more numbers (called SUVmax scores) which will give more insight into the aggressiveness of the disease,

For now - your prostate cancer (Grade 4 out of 5) - the NCCN guidelines recommend either RP or RT+ADT. (See attached chart.)
The cribriform pattern is an indicator of possibly more advanced disease.
You’ll need to discuss with your doctor whether RT+ADT or RP will work; and if you do RP, will you have to do RT+ADT anyway?
