Overview
PSA is a prostate protein measured in blood; a raised value does not equal cancer.
What is it for?
Screening concerns people without symptoms after individual discussion.
When is it considered?
Assessment based on age, family history and other risks.
Before your appointment
Discuss benefits, false positives and overdiagnosis; universal yearly testing is not a rule.
Procedure and preparation
PSA, examination and possible repeat testing, MRI or biopsy according to assessment.
Understanding results
Infection, prostate size and context affect results; no isolated threshold replaces clinical assessment.
Next steps and follow-up
Risk-based monitoring, further investigation or management of a confirmed diagnosis.
Three questions to ask at your visit
- What are the benefits and limitations of testing in my situation?
- What factors may affect interpretation?
- What is the next step for each possible result?
