Think about the above highlighted.
42% reduction in mortality if annual screening, means that every two years is just not good enough to pick up something that has just started to develop, or develops within that additional year to fatal. High survival rate when picked up in stage 1/2 , low survival rate when picked up in stage 4.

Now if it was currently every two years because of some hesitancy over that radiation dose, then makes the more incentive to get a simple blood test that can be done every year.

This has to be the best trough of water in a town at the edge of a desert. I dont have to convince my horse to drink it.
