I sure wish that the number of people that were back to normal was as large as you say, but unfortunately, it is not.

If someone has a Prostatectomy, The studies show a 16% to 46% 15-year cumulative incidence of BCR. The percentage risk is based on the risk factor of the surgery results. If someone has aggressive issues found in the prostate biopsy that can really raise the percentage chance of their having BCR.

Then there is radiation. Approximately 15–40% of men who undergo radiation therapy (RT) for prostate cancer develop biochemical recurrence (BCR) within 10–15 years. While some studies estimate the risk up to 50%, the rate heavily depends on pre-treatment risk factors, with studies showing 18% for low-risk, 24% for intermediate-risk, and 36% for high-risk patients over 15 years.
