Can national lung cancer screening programs be implemented without exacerbating social disparities?

Randomised trials established that low-dose CT screening reduces lung cancer mortality over a decade ago. However, population programmes remain limited, even in high-income countries. Lung cancer disproportionately affects socioeconomically disadvantaged populations. As screening expands, will equity be prioritised? Australia's programme illuminates a promising pathway, but the question remains: can reductions in mortality be achieved equitably?
