What would you do if PSA stayed at 0.15 after prostatectomy?

Hi everyone,

I am 58 years old. I had a radical prostatectomy seven months ago and my PSA never dropped to undetectable levels. It has stayed at 0.15 for the past three months.

One doctor recommends a conservative approach with low dose radiation to the prostate bed only. Another recommends a more aggressive plan with radiation to the prostate bed, glands, and lymph nodes along with hormone therapy (relugolix for 6 to 18 months).

I am torn between avoiding side effects now versus hitting it hard to lower long term risk. Has anyone here faced this decision? How did you choose, and do you feel it was the right call?

Thanks for any insight. I would really appreciate hearing your experiences.
