Lung cancer screening: what to know and how to get started

You can’t always see or feel the early changes that lead to lung cancer, but screening can. A simple, low-dose CT scan can detect small lung changes or nodules long before symptoms appear. Catching these early gives you and your clinician a real opportunity to treat lung cancer at a stage when it’s far more manageable, and outcomes are significantly better.

Understanding how and when to get screened can help you feel confident and in control of your long-term health.

You will learn:

• What lung cancer screening is and why it matters
• Who needs screening and how often
• What to expect before, during, and after a low-dose CT scan
• How Curative supports screening and helps you get started

What lung cancer screening looks for

Lung cancer screening checks for early lung changes, often tiny nodules, that could indicate early cancer or a higher risk of future cancer. Screening uses low-dose computed tomography (LDCT), a specialized imaging scan that takes detailed pictures of the lungs using much less radiation than a standard CT scan.

Low-dose CT scan (LDCT)

A low-dose CT scan is quick and painless. It uses X-rays to create cross-sectional images of the lungs and can detect very small abnormalities.

The test is:

• Non-invasive
• Fast (usually under 10 minutes)
• Done while fully awake
• No needles, contrast dye, or preparation needed

LDCT is the only recommended screening test for lung cancer.

Who should get screened?

Clinical guidelines recommend annual lung cancer screening for adults who meet all of the following criteria:

• Ages 50–80
• A history of heavy smoking (typically defined as 20 pack-years or more). Talk to your doctor about your smoking history to see if you qualify
• Are current smokers or have quit within the past 15 years

If you meet these criteria, your clinician may recommend a yearly low-dose CT scan.

Your timing may be different if:

• You have other risk factors (e.g., occupational exposures)
• You previously had abnormal imaging
• You have other lung conditions, such as COPD
• Your clinician determines a different follow-up interval is appropriate

Why screening matters

Lung cancer is often diagnosed at advanced stages because early disease rarely causes noticeable symptoms. Screening is essential because:

• It can detect lung cancer before symptoms appear
• Early-stage lung cancer is much more treatable
• Screening has been shown to reduce lung cancer deaths among high-risk groups

What to expect during a screening

Low-dose CT scan

1. You check in at an imaging center or hospital radiology department.
2. A technologist helps position you on the CT scanner table.
3. You lie still while the scanner moves around you for a few minutes.
4. There is no pain, and you can breathe normally.
5. You can return to normal activities immediately afterward.

If the scan shows something unusual, your clinician will discuss next steps, which might include repeat imaging or a referral to a lung specialist.

Most people find the experience quick and easier than expected.

Where you can go for screening

You can complete lung cancer screening through:

• A primary care clinician (for the referral and discussion)
• An imaging center that offers LDCT
• A hospital radiology department

Frequently Asked Questions

How long does a lung cancer screening take?

Most low-dose CT scans take less than 10 minutes.

Does the scan hurt?

No. The scan is painless and non-invasive.

Do I need screening if I feel fine?

Yes, if you meet the screening criteria. Early lung cancer rarely causes symptoms.

What happens if my scan shows something?

Your clinician will review the findings and help plan follow-up imaging or evaluation if needed.

How do I get started through Curative?
