The PSA test is a blood test used primarily to screen for prostate cancer. The test measures the amount of prostate-specific antigen (PSA) in your blood. PSA is a protein produced by both cancerous and noncancerous tissue in the prostate, a small gland that sits below the bladder in males.
PSA levels can be measured in the bloodstream, and elevated PSA levels can sometimes be a symptom of prostate cancer. So, this antigen gives doctors a starting point to evaluate your risk of having that disease. But what constitutes a normal PSA level? Why might your PSA levels be elevated?
Learn what a PSA test is, plus the limitations and potential harms of the test when used to screen for prostate cancer.
PSA testing for cancer screening may help detect prostate cancer early, when it's easier to treat and more likely to be curable. Testing can be done with a simple and widely available...
The PSA blood test can be used to screen for prostate cancer in men without symptoms. It’s also one of the first tests done in men who have symptoms that might be caused by prostate cancer. PSA in the blood is measured in units called nanograms per milliliter (ng/mL).
Cancer screening tests — including the prostate-specific antigen (PSA) test to look for signs of prostate cancer — can be a good idea. Prostate cancer screening can help identify cancer early on, when treatment is most effective. But it isn't perfect.
If you have low to intermediate risk prostate cancer, there are genomic tests that can better inform on the risk of developing a more aggressive cancer. These tests look at the DNA of your actual cancer cells to compare them to other men, to come up with an individual risk profile for you and your cancer. ... Prostate-specific antigen (PSA ...
Age 40 for men at even higher risk (those with more than one first-degree relative who had prostate cancer at an early age) After this discussion, men who want to be screened should get the prostate-specific antigen (PSA) blood test. The digital rectal exam (DRE) may also be done as a part of screening. (See Screening Tests for Prostate Cancer.)
What is a PSA test? A prostate-specific antigen (PSA) test measures the amount of PSA in your body. It’s a type of blood test that reveals if you have elevated PSA levels.PSA is a protein that your prostate gland makes. Normal and cancerous prostate tissue make PSA. But prostate cancer tends to produce PSA in higher amounts.. Healthcare providers recommend PSA tests for people assigned male ...
What is a PSA Test? The PSA test is the leading method of screening for prostate cancer. PSA screening can help catch the disease at an early stage when treatment may be more effective and potentially have fewer side effects.
