Then why not skip the PSA completely and just get a biopsy?
The biopsies are not without risk. How often do prostate biopsies correctly detect existing cancer? About half the time.
So why not just skip the PSA and skip the biopsy and get a prostatectomy...
The screening procedures for prostate cancer are not perfect, but they are designed to maximize disease detection and minimize unnecessary surgery. The protocols are statistically determined.
