If you've had your prostate removed, the "Phoenix" criterion for recurrence is at 0.2. The comment above to wait for 2.0 is only for those still with a prostate, having had radiation as a primary therapy.
The trend is more important than the value. A growth process generally doubles on a logarithmic trend, so if you plot your PSA levels vs time on a log plot it would be a straight-ish upward line. If that's happening, then it's likely to be growth and just a matter of waiting until you think it appropriate to do other analyses or treatments, along with your doctor's guidance.
Finally, I jumped in since you're also a G9. The G9 tumors, specifically the Type 5 cells, don't make much PSA. So comparing your PSA to that of, say, a G7 3+4 is misleading. Those put out much more PSA per gram of tumor tissue than a G9 does, like 3 or 4 times as much depending on the mix of Type 3,4, or 5 cells. If they're recurring at 0.2, then yours could be recurring at almost 1/4 of that. This factor is greatly neglected by urologists, since for better or worse there just aren't that many of us G9 cases. [Edit: this may be somewhat arguable, and is not discussed much today, but that's my ever-so-humble understanding. Here's a link
to a post from some time back talking about
All of which is to say I am in favor of an earlier and more aggressive response if the trend is supportive of any kind of growth process, even at a lower level. But that's just me....
55@Dx on 4/16/13. PSA 5.2, G9(5+4), PNI+, cT3a by MRI.
IGRT - 44 sessions (79.2 Gy, 50.4 Gy pelvic)
ADT2 - Lupron+Casodex (5/13-3/16)
8/13-5/16 <0.1 (ADT2)
5/16-3/17 recovering from ADT2
3/17-3/19 up and down, slow drift up ~ 0.6 - 1.0 (no TX)
4/19 - resumed ADT (due to slow up trend)
7/19 - <0.1 My Story
