PSA 0.05 

My PSA is maybe rearing its head after 15 years. An ultrasensitive test in mid-2020 was .02. In August it was 0.05 (different lab).

I saw a medical oncologist who specializes in prostate cancer. His advice: don't sweat it, we'll start monitoring every 3 months for a while, see if anything is really going on. I'll get tested again early next year.

Meantime, I've got lymphoma, and start seeing a specialist for that soon. Doesn't appear to be an immediate problem--the kind I've got is incurable, but highly treatable, and median survival times are now stretching out to 20+ years for it.  The close monitoring and scans by the hematologist (who works at the same practice as the prostate oncologist) should help insure neither cancer poses a serious threat anytime soon.
