I am 52 years old. Diagnosed on 08/17. My markers were very high PSA 1350. Much extension in my bones. Treated with Zytiga + Prednisone. The markers have been going down to 0.17 in the last three months.
Today after revision the PSA has risen to 0.19. And the bones do not clear up
My doctor says we're doing well. But the small oscillation of PSA has worried me. Is my concern reasonable?
