By regularly testing PSA it’s possible to detect early‑stage asymptomatic prostate cancer. PSA (prostate-specific antigen) is a protein produced by the prostate. Its level in the blood can be determined with a simple blood test. The specialists at Docrates recommend that men of 50 to 75 years of age have their PSA level checked each year in a PSA testing. If close relatives have been diagnosed with cancer, monitoring and testing should begin even earlier. Regular PSA testing helps to assess the cancer risk and the need for any further examinations. Sometimes PCA3 determination can provide additional information.

The significance of the PSA level should always be assessed in proportion to the size of the prostate. The larger the prostate, the higher the PSA level. Even quite low PSA levels can indicate cancer. The level of free PSA is significant in differential diagnostics when assessing benign and malignant lesions. The lower the free PSA level, the higher the risk of cancer. The following table shows the reference values for total PSA in different age groups and the relationship between the percentage of free PSA and cancer risk. The table is intended as a rule of thumb for the assessment:

Age (yrs) S-PSA ( µg/l )
40-49 less than 2,5
50-59 less than 3,5
60-69 less than 4,5
70-79 less than 6,5


Proportion of
free PSA (%)
Cancer risk (%)
0-10 56
10-15 28
15-20 20
20-25 16
yli 25 8
