What you should know
The prostate-specific antigen blood test measures a protein produced by prostate cells. PSA can be elevated for several reasons besides cancer, so the result needs context.
Why this matters
Screening is not one-size-fits-all. Some tests can find disease that would never have caused symptoms, while other results lead to additional testing. Clinicians can help weigh benefits against false positives, overdiagnosis, and possible treatment side effects.
People often encounter conflicting information about prostate cancer online. It is helpful to consider how a claim was studied, whether it comes from a recognized health organization, and whether it addresses screening, diagnosis, treatment, or supportive care. These are different questions that may require different medical decisions.
What to discuss with your care team
Ask how this topic relates to your age, personal and family history, previous tests, current symptoms, and healthcare goals. If a test or treatment is proposed, ask what the result could change, what uncertainties remain, and when follow-up is needed.
Ask what your PSA result means for your age, history, and prior results.
