In an editorial in today's NYTimes, Richard Ablin, who discovered PSA (the enzyme that is the target of the test), publicly disavowed the test, calling it a "hugely expensive public health disaster". He went on to detail the statistics: "American men have a 16 percent lifetime chance of receiving a diagnosis of prostate cancer, but only a 3 percent chance of dying from it. That's because the majority of prostate cancers grow slowly. In other words, men lucky enough to reach old age are much more likely to die with prostate cancer than to die of it." [emphasis added]
The cost of prostate hysteria comes to about $3 billion a year for the tests, plus the pain and discomfort and sexual dysfunction - and cost - of men treated unnecessarily.
One study found "1410 men would need to be screened and 48 additional cases of prostate cancer would need to be treated to prevent one death from prostate cancer."
Another study found "94% of the cancers detected with the routine PSA blood test would not cause death before the age of 85."
PSA testing is the perfect example of unnecessary care in this country.
