Hey Gents,
Been fighting this motha close to 15 years. When I became castration resistant, I started apalutamide 14 months ago. My PSA dropped from 13.4 to 1.0 over 10 months. I saw my MO last week and my PSA went from 1.0 to 1.5.
The doctor says not to worry as he tells me I need a new bone scan and CT. On a mathematical level, my PSA increased 50%, one can infer a 6 month doubling time. My PSA has never bounced up and down; if it starts rising it continues until some form of intervention. Should I be freaking out?
Thanks for your help!
