Prefacing the fact that nobody here is qualified to tell you what your next steps should be, the entire point of having the PSA checked every few months for the first couple of years is to check for anomalies or metastasis. You had your RARP the day before I had mine, my first post-op PSA came in at 0.07, with my urologist saying the 0.2 is where things get amped up - for me, it could be that a lower PSA causes concern for your urologist given that I was Gleason 7 versus your 9.

As an example of why I prefaced that comment: I've read on here numerous times that 0.1 was the threshold for more treatments, but in reality it's 0.2. Perhaps it was increased and some folks are still referencing the 0.1, but when I got my 0.07 I was a bit concerned that I was on the bubble and the slightest bump would put me into radiation - mostly based on reading that statement here. It turns out I was concerned about nothing, my urologist literally said "excellent" on his notes regarding the PSA test result.
