Hello, @fmcallister1954 Yes, it's scary when tests come back with a slightly higher PSA and I understand your alarm. My brother is being followed for prostate cancer (prostatectomy in 2020) and we've had many discussions about his treatment and what the PSA levels mean. I've been treated for uterine cancer and I also know how frightening it is to get back results that you did not expect. While you'd hope that the PSA number is exact and reliable there are many reasons why the number can change. This link from the American Cancer Society explains the fluctuations:

Are you being followed by an oncologist or the surgeon at the VA? How often do get a PSA? You mention a PSA test done in December 2020. And this new test is a year later. If you were my brother, I'd tell him to call the doctor who is following him and ask about this new PSA result. I would want to know the plan - should the PSA be repeated in 3 or 4 months to see if it changes?

Would you please come back here and let me know what you find out from your doctor?

No Oncologist is involved yet!! Contacted my Urologist and told him, has not responded yet, I am still considered < 0.02 very low. @ 0.016 that only 16 above 0.000 or none at all so it is very early yet. I will no doubt get rechecked in 3months.
