PSA test
The PSA test is a blood test that measures the level of a protein produced by the prostate, called Prostate Specific Antigen, or PSA. The test can help doctors to diagnose prostate cancer, as men with a high PSA level are likely to have cancer.
But men can have a raised PSA level without having cancer. And sometimes a man may have prostate cancer, but will not have a raised PSA level. Also, a PSA test cannot tell if a man's prostate cancer is likely to grow fast and need treating quickly, or if it will grow slowly and does not need treatment.
