Question: what are high psa levels?
Answer: The amount of PSA in your blood is measured in nanograms of PSA per millilitre of blood (ng/ml). If you're aged 50 to 69, raised PSA is 3ng/ml or higher. A raised PSA level in your blood may be a sign of prostate cancer, but it can also be a sign of another condition that's not cancer, such as: an enlarged prostate.
