Lung Cancer Surge: Non-Smokers at Risk, Environmental Factors Blamed

• Lung cancer is rapidly increasing, becoming an epidemic and the leading cause of cancer-related deaths globally, according to WHO.
• While smoking accounts for 85-90% of cases, there's a significant rise in lung cancer among non-smokers due to genetic and environmental factors.
• Secondhand smoke exposure increases a non-smoker's lung cancer risk, with studies showing a 27% higher risk for partners of smokers.
• Air pollution, particularly PM2.5 and PM10, is classified as a Group One carcinogen, increasing lung cancer incidence and mortality.
• Lung cancer in non-smokers is often driven by specific gene mutations (oncogene-addicted), allowing for targeted drug treatments.
