That's why looking at all common cancers as well is important. Leukemia and lung cancer are the opposite end of the spectrum - early intervention is critical for leukemia and most lung cancers. And the UK does a much worse job at treating those than almost all other developed countries, and particularly the US. So yes, some portion of the difference can be attributed to differences in screening practices, but screening practices are a relevant aspect of the entire system, and screening practices alone can't explain the UK's abysmal record for treating the more aggressive cancers which they do detect.
