I had PSA tests through the SRT, and about halfway through it started to drop. However, my rad onc said that it can take upwards of a year for the PSA to fully drop, and the only concerning issue is if the PSA continues to rise after treatment. If you have the same reading as before for some months afterwards, no need to worry. But if it rises at all (within measurement error, of course), then it is cause for concern.
