Even if you don’t smoke, you can still develop lung cancer. Here are the key causes:
1. Genetic Factors and Bodily Abnormalities
Adenocarcinoma, the most common lung cancer type in non-smokers, frequently affects East Asian women aged 40+.
A family history of lung cancer increases risk, even without smoking.
2. Secondhand Smoke (Passive Smoking)
Exposure to smoke in social settings (e.g., entertainment venues) or from family members who smoke.
Residual smoke on clothing or in living spaces can also contribute.
3. Dust, Incense, Cooking Fumes, and Industrial Chemicals
Incense smoke, charcoal stove fumes, and industrial chemicals like chromium, arsenic, and arsenic compounds (common in factories) increase lung cancer risk.
Prevention: Strict adherence to workplace safety protocols.
4. Proximity to Polluting Factories
Living near factories emitting toxic fumes or waste long-term.
5. Air Pollution (PM2.5)
PM2.5 particles are not ordinary dust—they contain carcinogens that irritate the respiratory tract and elevate lung cancer risk, even in non-smokers.
