Lung cancer can affect anyone, but smoking remains the leading risk factor, responsible for about 90% of all cases. This includes the use of cigarettes, cigars and pipes. The longer you smoke and the more you smoke each day, the higher your risk.
The good news is that quitting at any age significantly lowers your risk over time.
Other factors that can increase your risk of developing lung cancer include:
- Exposure to asbestos or other hazardous materials and chemicals
- Exposure to radon gas
- Breathing in secondhand smoke
- A family history of lung cancer
If you think you may be at risk, talk to your doctor about whether a cancer screening is right for you.
