Inhaling smoke from others' cigarettes regularly increases your lung cancer risk, even if you’ve never smoked a day in your life.
Secondhand Smoke
Air Pollution
Polluted air contains harmful chemicals and tiny particles that can enter your lungs and damage tissues, leading to possible cancer over time.
Radon Gas
This odorless, invisible gas naturally rises from soil. Trapped in homes, it’s the second-leading cause of lung cancer in non-smokers.
Jobs in construction, mining, or manufacturing can expose you to cancer-causing substances like asbestos, diesel fumes, and industrial chemicals daily.
Workplace Exposure
Family history can raise your chances of developing lung cancer, especially if close relatives have had cancer or inherited gene mutations.
