Lung Cancer: A Growing Concern in Singapore

Last updated: Jun 17, 2025

Lung cancer is still the leading cause of cancer-related deaths in Singapore. It causes more deaths than other cancers like colorectal cancer, which is the most common cancer diagnosed.

Recent information from the Singapore Cancer Registry shows a concerning situation: about 100 people die from lung cancer each month. This number is higher than the roughly 74 deaths each month from colorectal cancer, which is the second most deadly cancer. Even though colorectal cancer is diagnosed more often — about 204 new cases each month compared to 149 for lung cancer — the death rate from lung cancer is higher. This highlights the importance of improving screening methods for lung cancer in Singapore, especially for those who are at higher risk.

Late Diagnosis: A Challenge in Lung Cancer Treatment

A critical hurdle in lung cancer management is its late diagnosis. In Singapore, about 75% of lung cancer cases are detected at advanced stages (stages 3 or 4), significantly diminishing the chances of successful treatment. The absence of symptoms in early stages further complicates timely detection, making early diagnosis a rare occurrence.

The Case for Expanded Screening: Insights From Singaporean Experts

Professor Lee Pyng from the National University Hospital (NUH) is leading a change in how we approach lung cancer screening. Right now, screening mainly targets long-term heavy smokers, but Prof. Lee suggests we should expand it to include more people. This idea is backed by research from the National Cancer Centre Singapore (NCCS), which shows that almost half of lung cancer patients in Singapore are non-smokers.

Low-Dose Computed Tomography (LDCT): A Game-Changer in Early Detection

The introduction of low-dose computed tomography (LDCT) scans marks a significant advancement in lung cancer screening. Unlike traditional X-rays, LDCT is sensitive enough to detect early-stage cancers and uses a fraction of the radiation of standard CT scans.

Family History and Lung Cancer Risk

A key factor in assessing lung cancer risk is family history. Dr. Gillianne Lai of the National Cancer Centre Singapore (NCCS) underscores this point by citing a comprehensive Taiwanese study. This study provides evidence of the efficacy of screening among individuals with a family history of lung cancer.

The findings from Taiwan are particularly striking: out of 49,508 participants screened for lung cancer, 531 cases were detected, translating to a detection rate of 1.1%. More significantly, 85.1% of these cases were diagnosed at very early stages of the disease. These statistics highlight the crucial role of early detection in improving the prognosis of lung cancer patients.

Who Should Consider Lung Cancer Screening?

Early detection of lung cancer can significantly improve treatment outcomes. Given the recent findings and expert recommendations in Singapore, the following groups of people should consider undergoing lung cancer screening:

Long-time Heavy Smokers: Traditionally, heavy smokers have been the primary focus of lung cancer screenings due to their high risk.
Non-smokers With a Family History of Lung Cancer: As emerging studies suggest, non-smokers with a family history of lung cancer are also at a considerable risk.
Individuals Exposed to Second-Hand Smoke: Regular exposure to second-hand smoke is another significant risk factor.
People With Occupational or Environmental Exposure: Those exposed to certain substances like asbestos, radon, and other carcinogens in their work or living environments should also consider screening.
Age Factor: Older adults, typically those above the age of 55, are more likely to develop lung cancer, thus screening is often recommended for this age group.
Individuals With Chronic Respiratory Conditions: Those with a history of chronic respiratory diseases may also be at higher risk.
Lifestyle Factors: Diet, exercise, and overall health can also influence the risk of lung cancer.

This list is not exhaustive, and it's important for individuals to consult a doctor to better understand their specific risk factors and screening needs.
