"Can save lives" is not "will save lives"
That is the level of stupid that is being dealt with here.
Note: the evidence stacks up to provide at best tenuous support for routine PSA testing. Screening leads to a good deal of suffering, and it doesn’t save a lot of lives.
In other words, this rank idiot actually believes that pointing to some tests, means the idea at the aggregate is refuted.
Also note, this is an yet another example where a truncated quote is used by the rank idiot. Specifically: No one is denying that screening can save lives, but when it comes to screening policies for a population, public health officials must weigh the medical and economic costs and benefits across people of different risk levels
The rank idiot can't grasp (or is ignoring) what "for a population" means. Finally, notice the rank idiot can not, will not, respond to the clear conclusion regarding mortality rates.
Nobody reading is at all shocked.
