Does a high PSA result mean I have prostate cancer?
A raised PSA does not necessarily mean cancer. Benign enlargement, inflammation, infection and temporary factors can raise it, while some medicines affect the level. A clinician interprets it alongside age, symptoms and previous results and may recommend repeat or additional testing.

Before interpreting the number
Report urinary infection, recent prostate procedures and medicines, especially drugs such as finasteride that can lower PSA. Follow preparation instructions and do not stop or alter medication to obtain a different result.
What happens next?
A repeat sample may be taken after temporary factors settle, at a time chosen by the clinician. Persistent concern may lead to MRI, additional tests or biopsy. Decisions should not rely on one numerical threshold for every age and situation.
Avoid opposite assumptions
A high result does not prove cancer, and a low result cannot absolutely exclude it. Ask for an explanation and follow-up plan rather than ignoring symptoms. Inability to urinate, or fever with pain and urinary symptoms, needs prompt assessment regardless of the planned repeat-test date.
