I'm no doctor, but, here's my $0.02
Is there "any chance", unfortunately there's almost always a chance but there's also a good chance you're one of the lucky ones.
Given what I've learned from reading over the last couple years. I'd probably just keep an eye on the PSA. 5 is elevated for a 66 year old but not by a great deal. How fast PSA rises is an indicator but you're showing a 9 year period here. Your "rate of doubling" shown in your numbers is over 10 years. If my math is right, your increases are...the first two numbers are a 2 or 2+ year period, the third year it goes down then has an increase this year. There are a lot of things that can increase your PSA by small amounts.
2014 Baseline
2017 15.38%
2019 31.58%
2022 -5.56%
2023 28.00%
If the biopsy really got a core from the lesion, sounds like you've pretty much identified that as BPH. BPH can raise your PSA levels as well as PCa.
If it was me and I was concerned about it, maybe get a PSA test every three or six months for a year at this point, to see if the rise continues and at what rate it does so if it indeed does rise. Then if it continues to rise, or the rate increases perhaps another biopsy down the road.
For now, I'd take the "win" but just keep an eye on it. "Trust but verify"
Best of Luck to you sir!
I read prostate focal atrophy & inflammation can be a precancerous lesion. I wondered if it was worth sending pathology slides to Mayo.
