Rise in Lung Cancer Among Non-Smokers: Lancet Study Reveals Key Causes
Lung Cancer in Non-Smokers on the Rise
A new Lancet study reveals an increase in lung cancer cases among non-smokers, with air pollution being a major factor.
Lung cancer in non-smokers is growing, with adenocarcinoma making up 53-70% of cases globally in 2022. This type of cancer is weakly linked to smoking.
Who is Most Affected?
Lung cancer in never-smokers is now the 5th leading cause of cancer-related deaths worldwide. It is most common in women and Asian populations.
What are the main causes?
Experts say air pollution, passive smoking, workplace chemicals, household fumes, and genetics play a key role. Pollutants like PM, silica, cadmium, and chromium increase risk.
Expert Opinions
Dr. Gawande warns that long-term exposure to polluted air damages lungs. Dr. Shetty highlights that vehicular pollution and industrial toxins are rising concerns.
