There are problems with accuracy and presentation of statistical data in medicine so, from your data, you have twice the risk of serious harm from transrectal biopsy.
It apears that the EU is discouraging the use of transtectal biopsies for reasons of serious harm and acuracy
The point though of my post is that the changes to the provision of PSA testing for men (reduction) is based on balancing the "harm" done by diagnosis or treatment with - what? Well it would appear to be cost. Reducing the age range at which PSA screening is available on the NHS seems to be a way of condeming older men to die earlier than needed.
It is widely known that a sudden rise in PSA is a clear pointer of prostate cancer. This pattern can only be found by regular screening. So, my advice is to get a regular PSA done privately if necessary.
My assumtion is that the NHS isn't really worried about the cost of PSA testing but the cost of doing mpMRI scan where the PSA results indicate possible cancer.
