Lung cancer remains one of the leading causes of cancer deaths worldwide—not because it’s untreatable, but because it’s often detected too late. By the time symptoms appear, the disease is typically already advanced. But thanks to advances in imaging technology, early detection is now possible—through a tool called low-dose computed tomography (low-dose CT).
At Chinese General Hospital and Medical Center (CGHMC), we offer low-dose CT scans as part of our commitment to early cancer detection and proactive care. This powerful tool gives patients a better chance at survival by identifying lung cancer in its earliest, most treatable stage.
What Is Low-Dose CT and Why Does It Matter?
A low-dose CT scan is a specialized imaging test that uses minimal radiation to create detailed images of your lungs. Unlike a standard chest X-ray, a low-dose CT can detect very small nodules or tumors—sometimes as tiny as a grain of rice—before they cause symptoms.
The importance of this cannot be overstated. Early-stage lung cancer:
- Is more likely to be treated successfully
- Requires less invasive interventions
- Has significantly higher survival rates
In fact, studies have shown that screening high-risk individuals with low-dose CT reduces lung cancer deaths by up to 20% compared to those who don’t get screened.
Who Should Consider Low-dose CT Screening?
Low-dose CT screening isn’t for everyone—but it’s strongly recommended for people at higher risk of lung cancer. According to international guidelines and local best practices, you may be eligible if you meet the following criteria:
Age 50 to 80
Most screenings target individuals aged 50 and above, since risk increases significantly with age.
Current or Former Smoker
- Have smoked at least 20 pack-years (a pack a day for 20 years, or two packs a day for 10 years)
- Still smoking or quit within the last 15 years
History of Lung Disease or Family History
People with a personal history of chronic obstructive pulmonary disease (COPD), emphysema, or a family history of lung cancer may also qualify. If you fall into any of these categories, screening is not just optional—it could be life-saving.
What to Expect During the Scan
One of the major advantages of low-dose CT screening is how quick, painless, and non-invasive it is.
Duration
The entire scan takes only 5 to 10 minutes. There’s no need for injections or contrast dye.
Procedure
You’ll lie on a scanning table that passes through the CT machine while images of your lungs are taken. You may be asked to hold your breath for a few seconds to improve image clarity.
Radiation Exposure
The “low-dose” aspect refers to the significantly reduced radiation level used in this scan—about one-fifth of a standard diagnostic CT. For context, it’s comparable to the amount of natural radiation we’re exposed to over several months.
Are There Risks Involved?
While low-dose CT is safe and effective, it’s important to understand both the benefits and limitations.
Pros:
- Early detection: Catches cancer before symptoms arise
- Improved outcomes: Higher survival rates with earlier treatment
- Quick and easy: Minimal preparation and discomfort
Considerations:
- False positives: Sometimes, nodules are found that turn out not to be cancer, leading to further testing.
- Overdiagnosis: In rare cases, slow-growing cancers that may never become life-threatening are discovered, which could lead to unnecessary treatment.
- Radiation exposure: Although minimal, the scan does involve some radiation.
That said, for high-risk individuals, the benefits of screening far outweigh the risks. A short, low-risk procedure may lead to the detection of a cancer that could otherwise go unnoticed until it’s too late.
Why Choose CGHMC for Your Screening?
At CGHMC Imaging Services, we offer low-dose CT screening as part of an integrated, patient-centered cancer care approach.
What sets us apart:
Expertise in Early Detection
Our radiologists and pulmonologists are trained to evaluate even the smallest findings—ensuring accurate interpretation and minimal false alarms.
Seamless Coordination
Should your scan reveal any concerning signs, we offer immediate referral to:
- Pulmonology and oncology experts
- Biopsy and diagnostic services
- CGHMC’s Cancer Institute for full-spectrum treatment
State-of-the-Art Equipment
Our imaging department is equipped with modern, low-radiation CT scanners, ensuring quality imaging with your safety in mind.
Personalized Risk Evaluation
Unsure if you qualify? Our physicians can evaluate your personal risk factors and guide you on whether low-dose CT screening is appropriate for you.
When and How Often Should You Get Screened?
If you’re eligible, annual screening is recommended until:
- You reach age 80
- You haven’t smoked for over 15 years
- You develop health problems that significantly limit life expectancy or the ability to undergo treatment
Annual screening increases your chances of early detection. Skipping even one year could delay diagnosis until symptoms—and disease—have progressed.
