Smoking significantly increases the risk of lung cancer, a leading cause of cancer deaths worldwide. Understanding its impact is crucial for prevention.

Q: What is the connection between smoking and lung cancer?

• Smoking is the primary cause of lung cancer, responsible for approximately 85% of cases.
• Cigarette smoke contains over 7,000 chemicals, many of which are carcinogenic.
• The longer and more frequently a person smokes, the greater their risk of developing lung cancer.

Q: How much does smoking increase lung cancer risk?

Smokers are 15 to 30 times more likely to develop lung cancer compared to non-smokers.
