My grandfather was diagonsed with PC in 2015 at that time PSA was 76.he had TURP in 1998. After PC detection he is under treatment of Bicalutamide and Triptorelin 11.25mg after every 3 months and PSA reduced to near 0. Bicalutamide stopped in 2017.But we get diagonosed last month and PSA was about 1.3. Its rising again. I am worried about it . Does we continue with same treatment or should go with another. He also had 2 bone scan, which were clear.Kindly help.
