Beyond the Smoke: Understanding Lung Cancer in Non-Smokers

Why me? I have never smoked a cigarette in my life. This is what most of my non-smoker patients ask who believe that lung cancer is a disease of smokers. But the sad reality is 10-30 % of lung cancer occurs among non-smokers.

So, if it's not active smoking, then where lies the problem? That's a difficult question to answer. However, some are exposed to passive smoking, industrial air pollutants (like arsenic, asbestos, and chromium), environmental pollution, and indoor radon exposure. But are these the only causes? Not at all. Sometimes, it's a genetic problem and mostly idiopathic, which honestly means we have no clue what went wrong.

The most important question is, can we do anything about them? The answer is both Yes and No. Passive smoking is something one could consciously avoid. Environmental pollution – where do I begin? How often have we heard about ongoing efforts and talks trying to implement policies for a better future? I say we can only hope and pray for a better future. Regarding radon exposure, having a radon meter to monitor how much radioactivity is recorded per household is just over-ambitious thinking.

So, is there no ray of hope?….

There is. And that's in being the change from within. It is more of a mental awakening. Be more aware of the symptoms of caution and be proactive in seeking help.

Lung cancer symptoms can be subtle and often mimic other respiratory conditions. Non-smokers and healthcare providers should remain vigilant for:

• Persistent coughing > 3 weeks

• Unexplained chest pain

• New onset shortness of breath with exertion/at rest

• Unexplained unintentional weight loss

• Fatigue

• Coughing up blood (hemoptysis)

  
  

Once anyone has this, no self-medication or watchful waiting is recommended. SEEK THE RIGHT HELP. Meet a physician/pulmonologist, and they will get a Chest x-ray/ CT scan done. If the scan picks up something abnormal, we will go to the next evaluation level.

While many of the risk factors for lung cancer may be beyond our control, awareness is our greatest weapon. By staying informed and proactive, we take charge of our health. Let's pledge to recognize the signs, seek timely intervention, and spread awareness to safeguard ourselves and our loved ones.
