Prostate biopsy: What to expect?
in Health ·
I’m 46, and over the last three years, my PSA levels have consistently hovered between 2.0 and 2.5—one reading hit 3.0, but it settled back down to 2.5 after a few months. My fPSA/tPSA ratio has stayed between 8% and 12%. My DRE results are always clear, though I deal with some minor urinary issues—specifically a bit of an interrupted stream that stabilizes if I apply a little pressure to my bladder. My prostate is slightly enlarged, sitting at about 30cc. My urologist—I see him privately at a local clinic—is advising against a biopsy for now, suggesting we just stick to DRE exams and PSA checks every six months.
I’ve been digging through some medical journals online, and I found studies suggesting that even when a DRE is normal and PSA is under 2.5 with an fPSA/tPSA ratio below 15%, there’s still a significant risk—some say up to 50%—of finding cancer upon biopsy. I realize the standard clinical guideline is that this specific ratio is mostly used when PSA falls between 4 and 10 to help distinguish between benign enlargement and malignancy. However, there seems to be research indicating that even with "normal" PSA levels and a negative DRE, if that ratio dips below 15%, the probability of cancer shouldn't be ignored.
A couple of questions:
1. Should I go ahead with the biopsy? Isn't it better to be proactive rather than just monitoring my PSA and waiting for the next DRE?
2. Why isn't a biopsy recommended if the PSA hasn't spiked and the DRE looks fine? Is it because even if a biopsy comes back positive, the protocol might still just be "watchful waiting" until the PSA rises—meaning they wouldn't jump straight to removing the prostate anyway?
