The old " if correctly challenged, accuse of ignorance" tactic! Screening then a useless and costly exercise is what you are saying.. which we already knew .... as I said.
Your intransigence and myopic understanding of what screening is intended to be, could quite easily earn me my 1st ban.
I would respectfully suggest that you research and then try and actually understand what the goals and limitations of any medical screening program are. There is a reason screening programs are continuous and it is to ensure that where possible a false positve/negative on screen is picked up on the following screen.
Start there, even a limited screening program saves a health service an order of magnitude more in costs than it would spend in treating late stage diagnosis.
Let alone the lives saved by the early identification and ablation of cancerous or pre-cancerous cells in just cervical cancer cases.
