Prostate-specific antigen (PSA) - symptoms and how to test
Prostate-specific antigen testing (PSA) is a common method of prostate cancer detection. PSA, or prostate-specific antigen, is produced by healthy and cancerous prostate cells. The PSA blood test measures the level of PSA concentration in the blood. Typically, a blood sample is collected and sent to a lab for this testing. If you're considering getting a PSA test, it's best to talk to your doctor about the pros and drawbacks. When you're between 40 and 54, you should consider getting a prostate-specific antigen test.
