PSA Test Reduces Risk of Spread if Prostate Cancer Strikes
(HealthDay): "HealthDay - MONDAY, Oct. 25 (HealthDay News) -- Having a prostate-specific
antigen (PSA) test to screen for prostate cancer reduces the risk that if
cancer develops it will spread to other parts of the body, new research
indicates."
This article is saying that simply having a PSA test is a way of reducing the risk of prostate cancer spreading.
I assume that the author does not really believe that at all.
