The late detection rate changes from 70-80% with business a usual to about 20% with screening. That’s a pretty big advance. More than any new drug can provide.

That’s very sad. Unfortunately about 20% of people in a screening program are found when they already have stage 4, and the fact they get that way in <2 years also means they are ultra-fast growing. People not eligible for screening can also get lung cancer so it is a major step but not the panacea.

Absolutely. As Australia has universal cover AND this is free to all qualifying residents AND it’s an actual program that is promoted at federal and state level AND has support and leadership from Indigenous organisations, we should see an upswing in early cancer presentation in most groups.

The apple doesn’t fall far from the tree

Not to say this isn’t an issue and shouldn’t be studied for each cancer but I think this is not the smoking gun. We mainly do scans after curative surgery to screen for the next (hopefully) curable cancer. It’s rare to re-treat for cure unless it’s isolated recurrence suitable for surgery or radioTx

4 cancers, 10 different followup regimens, lots of “contamination” in controls and a broad conclusion. As for lung cancer, a single 2010 paper=pts never exposed to adjuvant, targeted, immunotherapies, stereotactic radiotherapy or minimally invasive surgery in a disease that was 90% fatal then
