I am going to give you my personal experience with this. A rising PSA number is what a poster posted previously as same a check engine light in your car. When it is rising it needs to be checked.

A rising PSA number can be caused by many issues. BPH and or prostate cancer. I had a normal PSA number but rising PSA number. My PCP did not like the rising numbers so did a PSA every 3 months. When it kept rising referred me urologist who did DRE and normal. Did MRI and found suspicious areas and biopsies diagnoses cancer.

That is my expereince with this and thus from my expereince I would asked for more frequent PSA test to see if continuing to rise versus doing it only once a year. Even if not cancer should consider BPH as many treatments out there to reduce it and proprably would reduce PSA.

Talk to your medical doctor about your concerns. Having a normal PSA does not mean you do not have cancer. Having a above normal PSA does not mean you have cancer.
Good luck

I would go with the 6 month suggestion offered by @xahnegrey40. It will give you more data points to chart the PSA velocity, which is more important than the raw number.
