If you want statistics you can't deny then I am sure there is a statistic saying how the rate of lung cancer increases in smokers rather than the rate of smokers increases with lung cancer. |
They way they did it ( I asked my own Doctor that question ) is by having people with Lung Cancer fill out a survey, they asked them about certain habits, and then based on what they marked off on that list they determine if there is a link.
They might ask if you ever smoked cigarettes.
Did you ever smoke a pipe.
Did you spend a lot of time outdoors or in your garden.
Do you have lots of dust in your house.
Do you have a pet cat.
Do you work at a chemical plant.
(and so forth) and then when they find out that 80 percent of them smoked a cigarette and only 10 percent ever smoke a pipe they use that evidence to claim that cirgarettes are a high risk and pipe smoking is a low risk. Etc. They might have a hundred things or activites on the list to mark yes or no for.
That is not real science nor real evidence. One reason is that back in the late 1950s when they conducted that fact finding survery nearly 80 percent of the population had smoked cigarettes. If they would have asked them if they watch TV then the evidence would prove that watching TV causes cancer of the lungs. (they did not ask). However they can say, using that survery evidence, that a there is a possible link between smoking and lung cancer, according to the stats.
So first off, before you go reading those claims, you need to know the difference between real science and those fact finding surveys. Because the survey does not give you any absolute or confirmed proof, it only provides a way to make a "educated guess". But if the survey did not ask the right questions, then it would be totally miss-leading. (simular to some of the polls created for this debate forum - such as the one for this particular thread ).
I checked out the survey and I do not think they included all the right questions that they should have asked. Nor am I sure if all those polled answered it honestly.
