Prostate Specific Antigen test, or PSA, is a blood test performed by your doctor that is designed to screen for prostate cancer. The normal function of PSA is to liquify semen and small amounts of this are found in the bloodstream. It is produced by normal tissue and prostate cancer.
High levels of PSA in the blood may be elevated in prostate cancer, inflammation, or infections. Interpretation of the test can be complicated and should be discussed with your provider.
PSA testing is done by physicians because prostate cancer is the most common cancer in men behind skin cancer. Although many prostate cancers may be slow growing, it is still the second leading cause of cancer deaths in men.
