My older brother got aggressive PCa around age 50. Consequently, I got the "get your psa test every year" talk from him back then and that's how I found mine before it got out of the prostate (even though I had both cribriform and IDC). Since I've been diagnosed, I've spoken with several of my friends and the general response is they're pretty ignorant of PCa and aren't even sure if they're getting a psa test during routine blood work. I certainly don't know, but I strongly suspect unless Biden had someone in his circle who had prostate cancer, he probably was just like everyone else; generally ignorant of it and just assuming their doctor was doing whatever was needed at annual physicals. Since it's now been revealed his last psa test was in 2014, it seems his providers were following the "stop testing over 70" guideline. Frankly, without my brothers experience I suspect I'd have done the same. Let's hope Bidens story helps generate more awareness of the changes needed going forward.
