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.
