lung cancer incidence rate
Cigarettes?…………..?
Proving cigarettes cause cancer is difficult because of which of the following: (you should click on all answers that apply)
1. just because rats may develop cancer when they are exposed to cigarette smoke does not prove that people will also develop cancer
2. just because you smoke does not mean that you will necessarily die earlier than someone who doesn’t smoke
3. you cannot simply look at those who smoked and those who didn’t and see which group had a higher cancer rate, because other linked factors (such as drinking coffee) might complicate the picture
4. If a group of 100 newly deceased people are considered — 50 who smoked and 50 who didn’t — the cigarette smoking group will have a higher incidence of lung cancer.
My grandparents are 88 and 83 and have been smoking for over 60 years, with no signs of quitting. They are healthier than most non smokers in their 50’s.
Just because people smoke is no reason to get all paranoid. People love to listen to these lab rats in Washington who are only paid to say what they are saying. Doesn’t make any of it true.
