Final answer:
The risk of lung cancer for smokers increases by 30%, changing the baseline risk from 6.67% (1 in 15) to approximately 8.67% when factoring in the increased risk due to smoking.
Step-by-step explanation:
According to the American Cancer Society, 1 in 15 men get lung cancer in their lifetime. With the risk for lung cancer increasing by 30% for smokers, we can calculate the increased baseline for smokers. First, we find 1 in 15 as a percentage which is approximately 6.67%. Then, we calculate the 30% increase on this baseline: 30% of 6.67% is about 2.00%. Adding this increase to the original baseline, the new risk percentage for smokers becomes 8.67%.
Therefore, the risk of a smoker getting lung cancer in their lifetime rises from the original 6.67% to about 8.67%. This calculation highlights the significant impact of smoking on lung cancer risk, emphasizing the importance of tobacco cessation for cancer prevention.
