A new meta-analysis published in the European Respiratory Review confirms that exposure to second-hand smoke (SHS) significantly raises the risk of lung cancer in people who have never smoked. The study found that prolonged and intense exposure to SHS increases the likelihood of developing lung cancer by 24%. The risk is particularly high in workplaces, followed by exposure at home.
Key Findings:
- Overall Risk: Non-smokers exposed to SHS had a 24% higher risk of lung cancer.
- By Setting:
- Workplace SHS exposure increased the risk by 38%.
- Home exposure raised the risk by 20%.
- Combined home and workplace exposure showed a 37% increase.
- Longer & Higher Exposure: The risk of lung cancer was greater with extended exposure duration and higher SHS intensity.
Why It Matters
Lung cancer remains the leading cause of cancer-related deaths worldwide, and SHS is a major yet preventable risk factor. This study underscores the need for smoke-free policies in workplaces and homes, aiming to protect non-smokers from the harmful effects of SHS.
