Found this story that lists overall cancer incidence by country.
Cancer rates: see how countries compare worldwide | News | guardian.co.uk
USA = #7
Netherlands = #12
UK = #22
Sweden = #26
Maybe there's something to that "switch to snus" thing?
This story shows smoking rates for males and females and lung cancer incidence for males and females by country for 2008.
Frank Davis - Smoking and Lung Cancer Stats
Sweden......17 23 19.4 18.1
USA...........25 19 49.5 36.2
Clarification: the numbers in the rows represent male smoking rate, female smoking rate, male lung cancer incidence, female lung cancer incidence. Smoking rates are percent of the gender and lung cancer incidence is per 100,000.
Puzzle: If Sweden has more female smokers than the US, why are the lung cancer rates so much lower?
