Why PSA may rise
Benign enlargement and inflammation can raise PSA as well as prostate cancer. Recent infection, procedures and medicines may affect interpretation. These circumstances should be reported alongside the number on the laboratory report. [1]
Is there one normal value for everyone?
No single PSA threshold separates cancer from its absence with certainty. Age, previous results, examination, family history and prostate characteristics are considered together. Comparing one person’s value with another’s cannot establish a diagnosis. A repeat measurement or other investigations may be appropriate. [1, 2]
Screening and symptom assessment differ
Testing someone without symptoms involves discussing the possible benefit of earlier detection alongside unnecessary investigations and overdiagnosis. Investigating urinary symptoms or following a known cancer serves a different purpose. The same blood test therefore does not answer the same question in every setting. [1]
What may follow an elevated result?
The clinician may review temporary influences, repeat the measurement where appropriate or consider MRI and biopsy. An elevated result does not automatically mean that a biopsy is required. Conversely, a low result does not exclude every possible risk. The next step depends on the overall assessment. [1, 2]
Preparing for the appointment
Bring dated PSA reports, a history of infections or procedures, a medicine list and details of prostate cancer in the family. Questions such as why the result may have changed, whether it should be repeated and what the next investigation would clarify make the discussion more useful. A sequence of results and the reasons for testing provide more information than an isolated value copied into an online comparison.
