The FPSA/TPSA is a higher than normal ratio of free prostate-specific antigen to total prostate-specific antigen, which is mainly used to screen for prostate cancer, especially in elderly men in their sixties who have a high index, considering the possibility of prostate cancer. If you are sure that there is an occupying lesion in the prostate gland on the ultrasound or MRI, you need to have a prostate puncture biopsy to take a biopsy for pathological examination, which is the gold standard for diagnosing prostate cancer.
