Understanding the PSA test

The PSA (prostate-specific antigen) test measures the level of the PSA protein in your blood. This can help find prostate problems and keep track of treatment. This section explains when and why the test is used, so you can make informed choices about your prostate health.

This chapter provides general information about PSA testing for prostate cancer. It is not a replacement for professional medical advice or treatment. Always consult your doctor or healthcare provider for guidance on your individual medical situation.
