What is PSA?

PSA (Prostate Specific Antigen) is a substance produced by prostate cells and is commonly used as a marker in prostate cancer screening. Its measurement is not a specific test for prostate cancer, and an elevated PSA level does not necessarily mean the presence of cancer. Non-cancerous conditions, such as benign prostatic hypertrophy (BPH) or prostate inflammation, can also increase PSA levels.

Why have a PSA blood test?

PSA blood testing is one of the first steps in prostate cancer screening. A blood sample is taken (you don't have to fast), and the PSA level is measured. Elevated levels may indicate a prostate abnormality, but this does not necessarily confirm the presence of cancer. It is all the more important to take the patient's age into account when interpreting PSA results; levels tend to increase naturally with age. On the other hand, high PSA levels in a younger man may be more worrying than high levels in an older man.
