My post-surgery PSA remained undetectable from the surgery in January 2011 through a routine follow-up PSA test in September 2015 when it was 0.05 ng/ml. It’s been bouncing around, creeping slightly upward every since.

I had 35 sessions of salvage radiation therapy 7 July 2022 – 26 August 2022 with concurrent androgen deprivation therapy (six-month dose of Eligard administered 3 May 2022), and that explains the drop in my PSA. I’m guessing that the bump to 0.13 ng/mL in March 2023 is from the Eligard wearing off and the radiation not yet kicking in.
