It is detectable because the test was able to detect it. When it is undetectable, you will see a "less than sign: <" in front of the number, as you did until July.
"Detectable" is different from "biochemically recurrent." Biochemical recurrence was quite arbitrarily defined in the last century as a confirmed reading ≥0.2 ng/ml. It was set at that level because the lowest PSA that could be detected back then was 0.1, so anything above that was considered to be meaningful. Now that ultrasensitive PSA tests can detect much smaller amounts, it may be time to re-visit that definition if clinical trials prove it is warranted to do so.
There is a lot of controversy, and no really solid data, about
what is the best time (i.e., at what PSA level) to have salvage radiation. No one wants radiation unless he really has to have it. On the other hand, one wants to have it before it is too late to be curative.

the best study I've seen that is applicable to men in your situation:
Low detectable PSA after prostatectomy – watch or treat?If your insurance covers it, the Decipher test may be a good decision tool for you.
