RX: The War on Cancer

An interesting post on cancer at 3 Quarks Daily notes how the high rates in North America are puzzling:

"[T]he incidence of lung cancer in Sweden with an average life expectancy of 80.3 years is less than half of that in the USA which has a life expectancy of 77.4 years ((22 versus 55.7 per 100,000 respectively) even though 22% adults smoke in both countries. This suggests that lifestyles may be important, but that smoking may not be the only important factor."
