Salvage radiation decision: with or without hormone therapy?

I had a prostatectomy in 2021. PSA was undetectable for 2 years. Then PSA went to 0.1 in 2023, and then 0.2 in 2024. I saw an Oncologist last month who recommends salvage radiation to the prostate bed. I will do that soon, but first need to make a decision on whether I should do hormone therapy with the radiation therapy. I have a family history of prostate cancer, and my PSA was fairly low (5.0) when I had the initial biopsy and diagnosis, which showed prostate cancer existed in all samples. The Gleason score was the bad 7. I had a PET scan and bone scan before surgery which did not show any signs of metastatic prostate cancer. So my question to the group is: should I do hormone therapy at this time? Or just do radiation and see if that works? I'm 64 and in good health.
