Post RP PSA .3; twelve weeks post RP, PSA .8

Had RP late January 2026, removed lymph nodes as well; pathology showed lymph nodes negative. Three weeks post RP; PSA at .3, 4 weeks later, PSA at .56; 12 weeks PSA .82.
Pathology Gleason was 9 with all of prostate cancerous.
Pre Op PET/MRI/Bone scans all showed no metastsis. I don’t like the sound of ADT/Radiation side affects; what if I don’t treat?
