Does PSA test detect all cancers?

Conversely, the PSA test doesn’t detect all cancers. About 20% of men who have cancer also have a normal PSA (less than 4 ng/ml), so the test may give some men a false sense of security.

What are the different types of PSA tests?

PSA exists in two main forms in the blood: complexed (cPSA, bound to other proteins) and free (not bound). The most frequently used PSA test is the total PSA, which measures the sum of complexed and the free PSA in the blood.

What are the Medicare guidelines for PSA testing?

All men over 50 are eligible to receive a free PSA test once every 12 months under the preventive services benefits included in Medicare Part B. If your doctor accepts Medicare assignment, you pay nothing. If your doctor does not accept Medicare assignment, you may pay a fee for the doctor services, but not for the PSA test itself.

Is PSA screening good?

The Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial reported no survival benefit with PSA screening and digital rectal examination, but the European Randomized Study of Screening for Prostate Cancer (ERSPC) found a 20% reduction in prostate cancer deaths.

Can PSA be elevated in prostate cancer?

Blood levels of PSA can be elevated in men with prostate cancer. For this reason, measurement of PSA in the blood has been used as a screening test for prostate cancer. However, the PSA test was first developed only to monitor men who had a history of prostate cancer. Views about PSA screening and appropriate follow-up have been evolving.

Why is PSA screening controversial?

PSA screening has always been somewhat controversial. That’s because PSA tests often alert doctors to the presence of cancer, but there is no precise way to determine, definitively, whether the cancers detected would have ever caused symptoms or harm during a man’s lifetime.

Is the PSA test curable?

Since its introduction in the late 1980s, the prostate-specific antigen (PSA) test has been hailed as a way to detect prostate cancer in its earliest, most curable stage. It has been called one of the most important tests a man can have. So why are many experts now stepping back, and even discouraging the use of widespread PSA screening?
