Lung Cancer, CARE2CURE

Overview

What is lung cancer?

Lung cancer is the leading cause of cancer death globally, and it's rising rapidly in India. While smoking remains the biggest risk factor, a growing number of cases are diagnosed in non-smokers, driven by air pollution, second-hand smoke, and occupational exposures. Early detection is challenging because symptoms often appear late, which makes awareness even more critical.

⚠ Risk Factors

Smoking (cigarettes, bidis, hookah, cigars), primary risk factor
Second-hand smoke exposure
Air pollution (PM 2.5 from traffic, industry, and biomass cooking)
Occupational exposure to asbestos, radon, arsenic, diesel exhaust
Family history of lung cancer
Previous radiation therapy to the chest
Personal history of tuberculosis or COPD
Indoor coal or wood smoke (common in rural Indian kitchens)

🔍 Symptoms to Watch

A new cough that doesn't go away after 3 weeks
Worsening of an existing chronic cough
Coughing up blood, even a small amount
Shortness of breath, especially with mild exertion
Chest pain that is sharp, dull, or constant
Hoarseness or persistent voice changes
Unexplained weight loss and fatigue
Recurring lung infections (pneumonia, bronchitis)

🩺 Screening & Detection

Low-dose CT scan: Recommended annually for adults aged 50–80 with a 20+ pack-year smoking history.
Chest X-ray: Not routinely recommended for screening, but used in symptom investigation.
Sputum cytology: Occasionally used in high-risk groups.
There is currently no broad population-wide screening for non-smokers in India, but awareness of symptoms is essential.

🛡 Prevention

Don't smoke. If you smoke, quit. Free helplines and apps can help.
Avoid second-hand smoke. Make your home and car smoke-free zones.
Reduce indoor air pollution, use cleaner cooking fuels (LPG, electricity) instead of wood or coal
Use air purifiers in polluted cities
Wear protective gear at jobs with chemical or particulate exposure
Test homes for radon if in high-risk areas
Eat a diet rich in fruits and vegetables

When should you see a doctor?

A cough that's lasted more than 3 weeks, coughing up blood, or unexplained breathlessness, see a doctor without delay. Don't dismiss it as 'just a smoker's cough.' Early diagnosis changes everything.
