Lung cancer is one of the most common types of cancer in the world. Yet, diagnosing it early significantly increases the chances of successful treatment. Lung cancer screenings are a crucial tool in detecting the disease before it progresses, especially for high-risk individuals. But what exactly happens during a lung cancer screening?
A lung cancer screening is a medical test designed to detect lung cancer at its earliest, most treatable stages. It is done using a specialized imaging technique called a low-dose computed tomography (LDCT) scan, which creates detailed images of your lungs. Unlike traditional X-rays, LDCT scans are more effective at identifying small nodules or abnormalities that could indicate cancer.
Doctors recommend lung cancer screening for individuals at high risk, particularly:
If you meet these criteria, scheduling regular screenings could be lifesaving.
Screening doesn’t just detect cancer; it saves lives. Studies have shown that LDCT scans can reduce lung cancer deaths by detecting tumors before symptoms arise. Here are key benefits:
It is equally important to talk to your healthcare provider to weigh the potential risks, such as false positives or unnecessary follow-up tests.
The first step in any successful screening begins with preparation. Here’s what you need to know beforehand:
Talk to Your Doctor
Before scheduling your LDCT scan, your doctor will assess your risk level. They’ll ask about your smoking history, family history of cancer, and any personal medical conditions, such as chronic obstructive pulmonary disease (COPD). Be honest and thorough—this information helps determine whether a screening is right for you.
Understand the Risks
Like all medical procedures, lung cancer screening has potential risks:
Your healthcare provider will explain these risks and address any questions, helping you make an informed decision.
Know What to Bring
For your appointment, wear comfortable, loose-fitting clothing without any metal (such as zippers or jewelry). Be prepared to share an updated list of medications and disclose any pre-existing conditions.
An LDCT scan itself is a quick and painless procedure. Here’s what happens during the test:
Checking in
When you arrive at the screening center, you’ll register at the front desk and confirm your personal information. Afterward, you’ll meet with a technician or radiologist who will explain the procedure.
The Scan
You’ll be asked to lie down on a padded table that slides into the CT scanner. The scanner is a large, doughnut-shaped machine with an opening in the center. During the scan:
Stay Still: The table will move slowly through the scanner while images of your lungs are taken. It’s critical to remain still so the images come out clearly.
Hold Your Breath: At times, you’ll be instructed to hold your breath for 5–10 seconds to help get accurate images. No Pain, No Needles: The test is non-invasive and doesn’t require injections or contrast dye.
The entire LDCT scan takes around 10 minutes from start to finish. Most patients describe it as stress-free.
Once the scan is complete, you’re done—at least for now. Here’s what to expect next:
Radiologist Review
A specially trained radiologist will review your LDCT results to check for any abnormalities in your lungs. They’ll look for signs of nodules, masses, fluid buildup, or other irregularities.
Getting Your Results
Your doctor will typically contact you within a few days to review your results:
Even if you receive a normal result, remember that lung cancer screening isn’t a one-time event. Regular screenings (usually once a year) are essential for individuals at high risk. If abnormalities are detected, don’t panic. Many findings on LDCT scans are benign, meaning they aren’t cancerous. Your doctor will guide you through next steps and provide the necessary care.
1. Is lung cancer screening covered by insurance?
Yes, most insurance plans and Medicare cover LDCT scans for eligible high-risk individuals. Check with your provider to confirm.
2. Can non-smokers get screened?
Lung cancer screening is primarily recommended for those with a history of smoking. However, if you have other risk factors—such as prolonged exposure to asbestos or family history—talk to your doctor.
3. Does the scan hurt?
Not at all! LDCT is a painless, non-invasive process.
4. What can I do to reduce my lung cancer risk?
Quitting smoking is the most effective way to lower your risk, followed by reducing exposure to harmful pollutants like radon and secondhand smoke.
Lung cancer screening could be the first step toward safeguarding your health. A test called lung cancer screening checks for lung cancer in the absence of symptoms. The suggested screening test is a low-dose computed tomography (LDCT) scan, which produces fine-grained pictures of the lungs with a low radiation dosage. When there is a history of smoking more than 20 cigarettes a day or stopped smoking less than 15 years ago. You might require more testing to determine whether you have cancer if the results of a screening test are abnormal. We refer to these as diagnostic assessments. By detecting abnormalities early, you empower yourself with better treatment options and peace of mind.
