NewScientist just published an article stating
“Pathologist Richard Ablin discovered the PSA antigen 40 years ago. He says it should never have been used as a cancer screening tool for all men“
The NewScientist article is ‘Prostate cancer test has been misused for money”
Richard Ablin’s book is “The Great Prostate Hoax: How big medicine hijacked the PSA test and caused a public health disaster”
Ablin says there are some very limited circumstances when the PSA test could be useful; such as after surgery for an actual prostate tumor.
However, in general the PSA test causes more harm than good.
If you buy the book, I urge you NOT buy it through Amazon since Amazon is now eagerly collaborating with the spooky NSA.
