What level of PSA indicates prostate cancer?

Table of Contents

Most men without prostate cancer have PSA levels under 4 ng/mL of blood. When prostate cancer develops, the PSA level often goes above 4. Still, a level below 4 is not a guarantee that a man doesn’t have cancer. About 15% of men with a PSA below 4 will have prostate cancer if a biopsy is done.

What is a dangerously high PSA number?

Although PSA levels between 4.0 and 10.0 are considered “suspicious,” there is only a 25% chance that you have prostate cancer. If your PSA levels are 10 ng/mL or higher, these levels are considered “dangerous.” This means your chances of having prostate cancer are 50%.

How fast does PSA rise with prostate cancer?

In the overall study population, the mean change in PSA levels was 2.9% per year and the rate of change in PSA increased modestly with age (P < . 001). Overall, men who developed prostate cancer experienced a more rapid percent change in PSA per year than men who did not (P < . 001).
