Has the cancer incidence gone down with drop in smoking rates?!


Question: Has the cancer incidence gone down with drop in smoking rates!?
The US smoking rate has gone down from half the population in the 50s to about 21% today!. I wonder if the cancer rate has gone down just as dramatically!.Www@Answer-Health@Com


Answers:
Getting statistics that go back that far isn't terribly easy (combined with the factor that people were still being killed by tuberculosis in the 50s)!.

Looking at the figures from 1980 onwards, the figures start at about 60 per 100,000, rise to about 70 per 100,000 by 1992 and drop back down again by 2005!.
Smoking rates, as you point out, are consistently falling during this period!.

So, smoking rates are falling (and the exposure to passive smoking is falling with all of the indoor bans), lung cancer rates are staying more or less the same!.

I'm sure that you can draw your own conclusions!.Www@Answer-Health@Com

Remember that lung cancer takes a long time to develop!.

The drop in rates may not become fully manifest for another 10 years or more!.Www@Answer-Health@Com

The incidence of the usually "smoking-related" cancers (lung cancer, bladder cancer) has indeed gone way down!.!.!.Www@Answer-Health@Com
