When people hear “lung cancer,” they think of smokers. But doctors increasingly see lung cancer in people who have never smoked. As the festive season brings more smoke and dust into the air, here is what you should know about air pollution and lung cancer.
Can Air Pollution Cause Lung Cancer?
Yes, it can contribute. Long-term exposure to fine particles in polluted air is recognised as a cancer risk and is linked to lung cancer even in non-smokers. Risk depends on how long and how heavily you are exposed, along with genetics and other factors. Living in a busy city does not mean you will get cancer, but it does mean the air deserves attention.
Other Hidden Risk Factors
Pollution is not the only cause. Passive smoking, indoor cooking smoke, workplace dust and chemicals, a family history of lung cancer and past lung disease can all raise risk. Many people overlook these because they assume lung cancer only affects smokers.
Warning Signs You Should Not Ignore
See a doctor if you have:
- A cough that lasts more than three weeks
- Coughing up blood
- Breathlessness or wheezing that is new or worsening
- Chest pain, a hoarse voice or repeated chest infections
- Unexplained weight loss or constant tiredness
Many people blame these on pollution or a cold and delay a check. A persistent symptom is worth investigating.
How to Protect Your Lungs in Mumbai
You cannot control the city’s air, but you can reduce exposure:
- Check the daily air quality index and limit outdoor exercise on poor-air days
- Wear a well-fitted N95 mask in heavy traffic, construction areas or crowded festivals
- Avoid burning waste and keep kitchens well ventilated
- Keep smokers out of your home and car
- Stay away from firecracker smoke during Diwali
When to Get Tested
If you have persistent symptoms or risk factors such as long exposure or a family history, speak to an oncologist about whether tests like a chest X-ray or low-dose CT scan are appropriate. Finding lung cancer early gives the best chance of effective treatment.
