The article dismisses a population-wide life expectancy increase of 4 months from one of the screens.

If that's your bar, then most preventative screening is probably not worthwhile.

If, say, only 5% of the people undertake that screening and manage to bring up the population expectancy by four months, then the actual effect could be over six years for screened individuals.

It's pretty dishonest to be confusing the effect of screening by counting unscreened individuals.

It's like claiming that seat belts don't work by looking only at fatality figures that don't inform to what extent seatbelts were worn.

It would really help me to use the same methodology but compare it to people smoking like they did in the 1980s.
