Can anyone explain this smoking/ lung-cancer graph, please?

Here.



It shows that whilst the rates of lung cancer for men has declined very much in line with the decline in the rate of smoking, the rates of lung cancer in women increased (albeit from a much lower level) even whilst the rate of smoking decreased.



Why is the effect of not smoking seemingly different in men and women?
