What is lung cancer screening?
Cancer screening is a test to check for disease in people who do not have any symptoms. Some examples of cancer screening include mammograms for breast cancer and colonoscopies for colorectal cancer. The goal of screening is to find cancer early when it is more treatable and even curable.
A lung cancer screening uses a low-dose CT (LDCT) scan and is quick and painless. This is the only proven method to screen for lung cancer.
If you believe you are at risk for lung cancer, talk to your healthcare team to see if an LDCT scan is right for you.

Lung cancer screening guidelines and criteria (USPSTF)
Lung cancer screening with a low-dose CT scan is the only proven method to detect cancer early—when it is most treatable and sometimes curable. We know this because researchers have been studying lung cancer screening by low-dose CT scans for many years. Survival rates more than double when lung cancer is caught early.
The U.S. Preventive Services Task Force (USPSTF) is made up of volunteer national experts who use scientific research to make national guidelines for preventive services, like cancer screenings.
The USPSTF recommends annual lung cancer screening for people who are:
- Adults aged 50-80 years, and*
- Those with a 20-pack-year smoking history, AND
- People who currently smoke or quit in the last 15 years
*Medicare covers ages 50 to 77
Low-dose CT (LDCT) lung cancer screening
What to expect
LDCT lung cancer screening is a simple, quick, and painless test for lung cancer. It requires no needles or dye, and you will remain fully clothed. In addition, there is no need to limit eating or drinking before the test. The entire appointment will only take about 10 minutes, while the actual scan takes about 1 minute.
How low-dose CT scans detects lung cancer
When you go in for an LDCT scan, a machine called a CT scanner will take 3D X-ray pictures of your lungs using a small amount of radiation. The radiation level is higher than a chest X-ray but much lower than other types of CT scans. Unlike a chest X-ray, which can detect some tumors, a low-dose CT scan is far more detailed. It can see spots on the lung as small as a grain of rice, and detect cancer at its earliest, most curable stage.
What happens after a scan
A radiologist with experience reading LDCT scans is the best person to read and report on your scan results. Once your results are in, your primary care provider will share the results with you.
• If a spot is found on your LDCT scan, follow up with your healthcare team for more testing and a plan for the next steps in your care.
• If your LDCT scan is normal, go ahead and make your appointment for next year.
Sometimes, more testing is needed after an LDCT scan to gather additional information. Tests could include a follow-up LDCT scan to see if a spot on the lung has changed over time. In some cases, a cancer test known as a biopsy is needed to know if a spot on the lung is cancer.
Lung nodules
LDCT scans can find spots on the lung called nodules. Nodules are also called lesions, coin lesions, growths, or solitary pulmonary nodules. Many people have lung nodules by age 50. Most nodules are not lung cancer and will never become lung cancer. However, lung nodules need to be watched over time to see if they grow or change.
Nodules are described by their features or how they look:

Lung cancer screening insurance coverage
For people who meet certain guidelines, a yearly low-dose CT screening for lung cancer is 100% covered by Medicare and most private insurance plans—just like mammograms and other screening tests. Additional testing and follow-up scans between screenings may have a cost, such as a co-pay or deductible.
Medicare
Medicare’s main guidelines for lung cancer screening are:
- Being aged 50–77 years
- Having no signs or symptoms of lung cancer
- Having a history of smoking for at least 20 pack-years (1 pack-year = smoking 1 pack per day for 1 year; and 1 pack = 20 cigarettes)
- Currently smoking or quit smoking within the last 15 years
- Receiving an order for lung cancer screening with a low-dose CT scan
Medicare has other guidelines as well, such as having a discussion with your healthcare team about lung cancer screening and whether you want to be screened or not. This is called shared decision-making and is required before your first lung cancer screening scan. Here’s the full list of Medicare screening guidelines.
Private insurance plans
Most private insurance plans cover lung cancer screening for people who meet the following USPSTF guidelines:
- Being aged 50-80 years, and
- Cigarette smoking history of at least 20 pack-years (one pack-year = smoking one pack per day for one year; and 1 pack = 20 cigarettes), and
- Currently smoking or quit smoking within the past 15 years
Even though most private insurance companies cover lung cancer screening when the guidelines are met, it’s important to check with your healthcare team or insurance company to confirm. The cost of lung cancer screening can vary depending on your insurance and eligibility. If you don’t meet the guidelines but think you’re at risk, talk to a member of your healthcare team about your options.
Benefits of lung cancer screening
“With no symptoms of lung cancer, I went in for a low-dose CT scan after receiving a direct mail flier from my health care provider system… early CT scans work!"

“My cancer was found early only because I was proactive... Lung cancer is an equal opportunity disease and early detection is a real lifesaver.”

Lung cancer risk factors
A risk factor for lung cancer increases the chance that you might develop the disease. The primary risk factor for lung cancer is cigarette smoking but it is not the only one. Other risk factors include environmental or on-the-job exposure to radon, asbestos, diesel fumes, and certain other toxins. Your family history, your lifestyle, and some health-related issues (such as chronic lung disease) can also put you at higher risk for lung cancer. If you are on active duty or a military veteran, you may have been exposed to burn pits, Agent Orange, or other toxic substances that also increase your risk.
Learn more about risk factors and whether you might be at risk. Talk to your healthcare team about whether lung cancer screening is right for you. Early detection of lung cancer saves lives—and could save yours.

What are lung cancer screening guidelines?
Lung cancer screening guidelines and guidelines is set by the US Preventive Services Task Force (USPSTF). The USPSTF recommends annual screening for lung cancer in adults aged 50 to 80 years who have a 20-pack-year smoking history and currently smoke or have quit within the past 15 years. If you have Medicare, their guidelines are slightly different. Medicare covers up to age 77 rather than 80.
What if I do not meet the screening guidelines but have other risk factors?
You should meet with your healthcare team to discuss your concerns.
What is a low dose CT-scan?
A low-dose CT scan uses the least amount of radiation exposure necessary to capture detailed images of your chest. This takes about 1 minute, does not use needles or injections, and there is no preparation required.
