Ray...cutting the PSA in half within three months is fine in my opinion. I think you're doin' great and hopefully your RO will agree.
Age 62 (64 now), G 3 + 4 = 7, T1C, PSA 4.2, 2/16 cancerous, 27cc. Brachytherapy 12/9/08. 73 Iodine-125 seeds. Procedure went great, catheter out before I went home, only minor discomfort. Everything continues to function normally as of 9/10/10. 6 month PSA 1.4, 1 year PSA at 1.0. My docs are "delighted"! My journey:
