Let me at the outset tell you that these readings of PSA for your age group are normal and not worrisome at all. This does not denote cancer prostate.
Following are some facts about the PSA;
1) PSA can rise because of the following;
a) Benign prostate hyperplasia
c) Cancer prostate
d) Any stimulation of prostate like sex, instrumentation, catheterization.
2) PSA is a poor screening method for the cancer prostate so it has false positive as well as false negative results for the screening of cancer prostate. This means that there are some patients with the cancer prostate who don't have raised PSA and there are patient who have raised PSA, with no cancer.
For exceptionally rare circumstance of it being cancer, I can assure you that it is treatable. There is a saying for prostate cancer; it never kills, people have absolutely normal life span.
