A study published in the British Medical Journal suggests that the Prostate-specific antigen (PSA) test to scan for prostate cancer may have no bearing on life expectancy. The PSA test measures the level of the PSA protein in the blood; a high reading may indicate prostate cancer.
The study followed about 1,500 Swedish men for 20 years, some of whom were screened by a digital rectal exam and others by the PSA blood test, which is generally a part of the annual physical for most men. The study concluded that “After 20 years of follow-up the rate of death from prostate cancer did not differ significantly between men in the screening group and those in the control group.”
If these findings are valid, why is the PSA test so accepted in conventional medicine? Mike Adams, the self-named “health ranger,” thinks he has the answer:
The reason PSA tests are so popular is precisely the same reason that flu vaccines are so heavily pushed: Because modern medicine pushers suffer from a deeply-ingrained cult-like irrational belief in everything they were taught in medical school, regardless of whether it has any basis in fact. PSA tests, in other words, are a kind of medical voodoo which works no better than sticking pins in a rag doll.
Adams contends that nutrition and lifestyle choices can be more effective than relying on screening tests in general.
