Watchful waiting is sensible but the "watchful" part is essential.
The time trend of PSA readings is very different for prostatitis and prostate cancer. If you have prostatis then it will likely come down pretty quickly once you get on the right antibiotic. Or it might jump around if it is resistant to antibiotics, or if it recurs. The one thing that prostatis is NOT likely to do is give you a PSa that grows slowly and steadily.
If you have prostate cancer you will likely see a fairly continuous though slow rate of rise. I would definitely NOT go away for five years and then test it again but although PC is quite rare in men your age it does occur, and when it does, it needs to be detected and treated.
For example, if you get a follow PSA test every six months, and let's say it goes up somewhat steadily 10-20% each time, never going down much, then after four tests like this that would be a pretty good indicator of cancer or a very unusually early onset of BPH. Either way it would be justification for a more extensive investigation, whether a biopsy or MRI or some of the advanced blood tests that are available these days.
The usual cutoff is 4 but that is a very arbitrary number, and your doc is right to be concerned given your number at your young age. 4 makes sense as a cutoff in a 60 year old. But the time trend gives you a lot of information and should not be ignored just because the number is less than 4.
it is extremely unlkely that your symptoms are PC related, because symptoms generally only emerge when people's psa is way higher yours - 10x or 100x or even more in some cases. However, there are a few rare cases of prostate cancer that don't throw much PSA. so it is not impossible, just very rare. But if you keep working with your urologist to find out why you are having the symptoms you are having then you'll figure it out.
FWIW, my annual numbers over six years were like this: 1, 1.3, 1.6, 2.0, 2.7, 3.6. At that point, given the time trend I got biopsied and found I had PC. The urologist said that my GP should have referred me out sooner given the regularity of the time trend.
