What is the PSA blood test?
PSA is a protein produced by both normal and cancerous prostate cells. It is normal for all men to have some PSA in their blood. A high level of PSA can be a sign of cancer. But your PSA level can also be raised in prostate conditions that are not cancer (are benign) or infection.
A PSA test on its own doesn’t normally diagnose prostate cancer. There is evidence from the research that doing a PSA test doesn’t saves lives. Your GP will discuss the test with you
