Lung cancer remains one of the leading causes of cancer-related deaths worldwide — including in Thailand. It predominantly affects older adults and those exposed to high-risk factors such as smoking and air pollution. Often called a “silent disease,” lung cancer may not show symptoms until it reaches an advanced stage, making early detection crucial for effective treatment.

 

What is Lung Cancer?

Lung cancer develops when cells in the respiratory tract developing abnormal and uncontrolled growth. The primary causes include:

• Smoking (including second-hand smoke)
• Air pollution, particularly fine particulate matter like PM 2.5
• Occupational exposure to hazardous chemicals
• Abnormal gene mutations (somatic mutations)

 

Early Warning Signs You Shouldn’t Ignore:

• Persistent cough, possibly with blood-streaked phlegm
• Shortness of breath or fatigue with minimal activity
• Chest discomfort, especially when lying down
• Unexplained weakness or neurological symptoms
• Abnormal bone and muscle pain
• Significant weight loss

If you or a loved one experiences any of these symptoms, it's important to consult a healthcare professional promptly for proper evaluation.

 

The Importance of Early Screening

Early detection can dramatically improve treatment outcomes. At Bumrungrad Hospital, we utilize Photon-Counting CT Scan — the latest advancement in diagnostic imaging — to detect lung abnormalities at their earliest stage.

This cutting-edge technology offers:

• Ultra-high image resolution
• Exceptional sensitivity in detecting small lesions
• Improved accuracy for early-stage diagnosis

 

Who should consider lung cancer screening?

This screening is especially recommended for individuals at high risk, including:

• Long-term smokers (e.g., one pack a day for over 20 years)
• Former smokers who quit within the past 15 years
• Adults aged 50 and above with regular exposure to air pollution

** Currently, there is more researches reported that family history of lung cancer (1^st and 2^nd degree relatives) increased of lung cancer risk (more numbers related to higher risk).  

New Advances in Lung Cancer Treatment

Recent medical innovations have transformed how we treat lung cancer. Options such as Targeted Therapy and Immunotherapy are now available, providing more precise and effective treatment with fewer side effects compared to traditional chemotherapy.
By analyzing genetic mutations in cancer cells, our specialists can develop personalized treatment plans tailored to each patient's condition.

 

Steps You Can Take to Prevent Lung Cancer:

• Avoid smoking and second-hand smoke
• Limit exposure to PM 2.5 and wear protective masks in high-risk areas
• Undergo regular screenings if you fall into a high-risk group
• Maintain a healthy lifestyle through exercise and a balanced diet
