I have seen the cancer study before ironsides. However, it leaves a few questions unanswered. It shows you the survival rate among those diagnose with Stage 1 or Stage 2 cancer. However it does not tell us what proportion of cancers were detected at Stage 1 and Stage 2, and what proportions were detected at Stages 3 and 4.
Now, I am only guessing here, but my guess would be that more cases are detected at stages 1 and 2 in Europe and Canada, compared to USA, and more cases are detected at Stages 3 and 4 in USA, compared to Europe and Canada. The reason I say this is that preventative medicine is lot less prevalent in USA compared to other counties (in USA there usually would be a co-payment, which is not present in other countries; it probably acts as a disincentive.
If that is the case, the study gives us only incomplete picture. Incidentally, the study also says that survival rates are high in Canada and Australia.
Second point is, cancer survival is only part of the story. This probably shows that USA spends a lot more on cancer than other countries do; you get what you pay for. However, that success does not extend to other categories, as the life expectancy figures tell us.
Excelling in one particular area, though admirable does not tell the whole picture, overall picture is still pretty dismal for USA.
