This connects directly to something I've talked about in the books and on YouTube: the single PSA reading isn't the whole picture.
My friend had a PSA that went from 4 to 9 in 9 months. The trend was worrying. A biopsy confirmed cancer, and he was successfully treated. Ber sure to keep track of your PSA values.
A new algorithm developed at the University of South Carolina — now being licensed for commercial development — formalizes something that experienced urologists have known for a while: the rate of rise in PSA over time (PSA velocity) is often more informative than the number itself.
The algorithm analyzes the shape of your PSA curve across multiple measurements. Aggressive prostate cancers tend to accelerate — the slope gets steeper. Benign causes like BPH or inflammation tend to produce a slower, flatter rise. Two men with the same current PSA level may have completely different clinical pictures once you look at how they got there.
It's not widely available yet as a standalone clinical tool — it's being commercialized now. But the principle is immediately actionable: at your next appointment, ask to see the PSA history, not just the current result. Most clinics have it on file. It just doesn't always make it into the conversation.
Has anyone here been tracking their PSA numbers over time? How long a history do you have, and has any doctor ever walked you through the trend rather than just the latest reading?
