What to do

I was diagnosed with Prostate Cancer in 2014. I had the robotic surgery and PSA continued to creep upward. I then had the Radiation treatment in 2016. Have had a PSA test every 6 months since then. Each time, it climbs at least .1%. I was told to move test to every 3 months and PSA climbed .3%. At this time it is .9. My Radiologist  has discussed possible Hormone Therapy if it continues to climb. I am 60 years old and in very good shape. What can I expect from this or is there another option?
