I have the usual urinary symptoms and some pain, but nothing else.
What do you mean by this? It is not "usual" to have pain when urinating, or any other "symptoms."
Your are correct that PSA doubling time is NOT meaningful or informative in untreated men because there are multiple likely contributors to PSA in your blood...and it sounds (based on your comment above) like you've got some of that going on. You should try to eliminate that, first...I would not suggest jumping to a biopsy without that, first. Advanced PC could cause those symptoms...you do NOT have advanced PC; you've got something else going on and there are several possible causes. Did you tell your urologist about
Here's the thing...you probably DO have some low-level PC simply because it is a natural part of aging. about
60% of 60-year olds have it, and most never know about
it and it never affects them...if they did discover it (based on running into circumstances which lead to a biopsy), the most of them would be the low-grade PC which no treatment is recommended. The 4K test sounds like a good next step for you; not biopsy. (Yes, another biopsy very well may be in your future...not now.) Before jumping to the 4K, did your PSA test also provide a "free PSA" result? You may have additional informative info before doing anything else. Don't rush...
