- both proton and Da Vinci machines would not be profitable without frequent billings for prostate treatments
- most males will have prostate cancer if they live long enough and not be aware of it or die from it. the odds of having low grade prostate cancer increase expotentially as a male ages ( I think an 80 year old has about an 80% chance of having prostate cancer)
- 1 in 500 will have aggressive prostate cancer and probably die from it
- there is no good test to tell the difference between aggressive and low grade prostate cancer

You may want to throw the book away, it's out dated.
The FDA has approved the PSA test.
There are GREAT tests to tell the difference between low grade & aggressive PC. Example: Decipher's Prostate RP Genomic Classifier.
