A college student who smokes asks a healthcare professional if there really is a connection between smoking and lung cancer. What is the healthcare worker's best response?
a. The risk for lung cancer for smokers than for nonsmokers is 5 times greater.
b. The risk for lung cancer for smokers than for nonsmokers is 10 times greater.
c. The risk for lung cancer for smokers than for nonsmokers is 50 times greater.
d. Lung cancer affects smokers and non-smokers equally due to occupational hazards.
B
The risk for lung cancer is 10 times greater for a person who smokes than for a nonsmoker. Ex-posure to secondhand smoke increases the risk for lung cancer in the nonsmoker and worsens other pulmonary problems such as asthma or COPD: 5 times is too small; 50 times is too great. Lung cancer does not affect smokers and nonsmokers equally
