Probably best to ask your oncology team. Everyone here is well-intentioned, and obviously we spend a lot of time reading about this new disease we have to live with, but you shouldn't worry too much about our amateur assessments of your test results. 🙂

Best wishes!

Even if it was 300.

The standard is that the PSA should drop to near undetectable, usually below .5 after radiation, much less 9 months after.

You should be speaking to a genito urinary oncologist about this. They specialize in prostate cancer and keep up with everything going on. A medical oncologist is not sufficient.

Your PSA is way too high after radiation, it implies there is something else going on.
