Understanding Lung Cancer Screening
Lung cancer is one of the leading causes of cancer-related deaths, but early detection significantly improves treatment outcomes. Lung cancer screening is designed to identify signs of cancer before symptoms develop.
What Is Lung Cancer Screening?
Lung cancer screening typically involves a low-dose computed tomography (LDCT) scan, which produces detailed images of the lungs. This scan can detect:
Small nodules or growths
Early-stage tumours
Other structural lung abnormalities
LDCT is more effective than traditional chest X-rays in detecting early lung cancer.
What to Expect from a Lung Cancer Screening
When you attend a screening, you can expect:
A health and risk factor consultation
Guidance on eligibility (age, smoking history, etc.)
A quick, painless low-dose CT scan (takes about 5–10 minutes)
Radiologist review and interpretation
Results delivered with follow-up recommendations if needed
No needles, injections, or special preparation are required.
Who Conducts This Service
Lung cancer screening is carried out by:
Radiologists and radiographers in imaging centres or hospitals
Pulmonologists or respiratory consultants (if further evaluation is needed)
Trained nurse practitioners or screening specialists
All professionals adhere to national screening guidelines and best practices.
Who Might Need This Service
You may benefit from lung cancer screening if you:
Are aged 50–74
Have a history of smoking (current or former smokers)
Have significant exposure to asbestos or radon
Have a family history of lung cancer
Experience unexplained symptoms like chronic cough or weight loss
Screening is recommended annually for those in high-risk groups.
Types of Lung Cancer Screening
Low-Dose CT Scan (LDCT) – the gold standard for early detection
Chest X-ray – sometimes used for follow-up but less sensitive
Sputum cytology – examining mucus (rarely used today)
Your healthcare provider will guide the best option based on risk profile and history.
Risks Associated with Lung Cancer Screening
While LDCT is generally safe, some risks include:
False positives – leading to unnecessary follow-up tests or anxiety
Radiation exposure – though minimal, it's still higher than a chest X-ray
Overdiagnosis – detection of abnormalities that may never become harmful
Incidental findings – other lung or chest conditions detected unintentionally
All screenings follow strict guidelines to minimise risk and provide clear next steps.
How to Choose the Right Health Professional
When booking lung cancer screening:
Choose providers using low-dose CT technology
Ensure staff includes qualified radiologists with lung imaging expertise
Ask about eligibility assessments and follow-up care
Check for national screening programme affiliation (if applicable)
