PSA (Prostate-Specific Antigen) Test

The PSA test measures the level of prostate-specific antigen in the blood, a protein produced by the prostate gland. Elevated PSA levels can indicate prostate issues such as enlargement, inflammation, or cancer, but they are not definitive alone. The test is commonly used to screen for prostate cancer, monitor treatment effectiveness, or check for recurrence. Factors like age, prostate size, or infections can influence PSA levels. It's important to interpret the results within the context of other diagnostic tests and a healthcare professional's assessment to determine the appropriate next steps.
