31 july 2026 Punjab Khabarnama Bureau : On World Lung Cancer Day, health experts are urging people—especially those at high risk—to understand the importance of early screening, recognise warning signs and seek timely medical evaluation. Early detection can significantly improve treatment outcomes and survival rates.
Who Should Consider Lung Cancer Screening?
Doctors generally recommend annual low-dose CT (LDCT) scans for people at high risk of lung cancer. Screening may be appropriate for individuals who:
- Are 50 to 80 years old (depending on national guidelines).
- Have a significant history of cigarette smoking.
- Currently smoke or have quit within the past 15 years.
- Have other risk factors as advised by a healthcare professional.
People without major risk factors are generally not advised to undergo routine screening unless recommended by their doctor.
Common Warning Signs
Lung cancer often causes no symptoms in its early stages, but warning signs may include:
- A persistent cough that does not improve.
- Coughing up blood.
- Chest pain.
- Shortness of breath.
- Hoarseness.
- Unexplained weight loss.
- Persistent fatigue.
- Recurrent chest infections.
Anyone experiencing these symptoms should seek medical advice promptly.
Major Risk Factors
The leading risk factor is tobacco smoking, but lung cancer can also occur in non-smokers. Other risk factors include:
- Exposure to second-hand smoke.
- Air pollution.
- Radon gas.
- Occupational exposure to asbestos or certain chemicals.
- Family history of lung cancer.
- Previous radiation therapy to the chest.
Why Early Detection Matters
Lung cancer detected at an early stage is more likely to be treated successfully. Regular screening for eligible individuals can help identify cancer before symptoms develop, improving the chances of effective treatment.
Prevention Remains Key
Experts recommend avoiding tobacco use, reducing exposure to environmental pollutants, maintaining a healthy lifestyle and discussing personal risk factors with a healthcare provider.
