Hi
My PC history is similar, RP, RT then a slowly rising PSA
Ive had 3 PSMA scans over the last 3 years with PSA's of 1.5, 2.1 and 2.9 but all negative
My oncologist is suggesting a 6 month HT, not sure which drug until we speak next week
I would certainly try and get a PSMA scan to see if that finds anything
Good luck to all
