UC Davis study: PSA testing for prostate cancer plays important role
Sacramento Bee

UC Davis researchers say that a widely used test for prostate cancer likely plays an important role in catching the disease early, when it is most treatable.

The findings suggest that the PSA – or prostate specific antigen – test could be responsible for a reduction in prostate cancer mortality rates.

Since the introduction of PSA testing in the late 1980s, prostate cancer mortality has gone down 40 percent. The higher the PSA level, the more likely a man has prostate cancer.
