Understand PSA Density to Gauge Prostate Health
Prostate size increases with age, leading to higher levels of PSA in the bloodstream. For men around 50, a typical prostate weighs about 25 grams, with a safe PSA level under 2.5, resulting in a PSA density of 0.1. As men age to 60, average prostate size increases to about 40 grams, maintaining the same PSA density at a PSA level of 4. However, a scenario arises when the PSA level exceeds what's expected for the prostate size; for instance, if a man's prostate remains at 25 grams but his PSA is 5, it indicates a higher PSA density, raising the potential for health concerns. This density serves as a strong indicator of prostate-related issues.
