Just another suggestion where statistics can show anything one wants (well most).

[skin cancer is often correlated with increased sun-exposure; I'm surprised no-one has considered a correlation with increased use of sun-creme (chemicals massaged into the skin].
Okay - now back on topic please.]

Off-topic reply....Not everybody uses sun-cremes, surveys can be done to gather the percentages of those who tend to use sun-cremes and those who do not and determine if the skin cancer incidence follow a usage trend versus an exposure trend. Whether or not such surveys have been done, I don't know, but I expect laboratory (animal) test have been done for the relevant chemicals on the skin of lab rats...
