Lung Cancer Screening

We’re here for you and appointments are available

If you have questions about a lung cancer screening appointment, please call 314-747-3046. Newly diagnosed patients also may call the registered nurses in our Patient Care Coordination Center, toll-free at 800-600-3606. The PCCC is open on weekdays from 8 a.m.-4:30 p.m.

Lung cancer often doesn’t cause symptoms, which makes regular screenings (if you’re eligible) vitally important. It also makes catching lung cancer in its earlier and more treatable stages more likely. Lung cancer is the leading cause of cancer death in the U.S. Many of these deaths could likely be prevented by early detection through screening. Siteman is committed to lowering the risk of dying from lung cancer, while reducing the potential harms of screening.

Our carefully designed program includes:

  • Screening recommended only for those likely to benefit
  • Follows U.S. Preventive Services Task Force, Centers for Medicare and Medicaid Services, National Comprehensive Cancer Network, and American College of Radiology guidelines on lung cancer screening
  • Dedicated Nurse Navigator to assist patients and their health care providers throughout screening and follow-up
  • Interpretation by skilled thoracic radiology subspecialists at the Mallinckrodt Institute of Radiology
  • Standardized reporting using the American College of Radiology Lung-RADSTM system
  • Same day or next morning screen interpretation
  • Negative results mailed to patient and primary care provider
  • Abnormal results phoned and mailed to patient and primary care provider by the Nurse Navigator
  • Automatic referral to a Washington University thoracic surgeon to monitor and manage abnormalities that may be caused by lung cancer
  • Emphasis on smoking cessation

Call 314-747-3046 to schedule your lung screening. Contact your doctor first for a referral.

What to expect at your lung screening



Our lung cancer specialists

Our lung cancer screening program is the largest in Missouri, comprised of 12 fellowship-trained thoracic radiologists. Seven of these experts were members of the original National Lung Screening Trial (NLST), a lung cancer screening study. The study compared low-dose helical CT and standard chest X-ray as lung cancer screening methods. The study was published in 2003 in the New England Journal of Medicine. The NLST was a defining moment in lung cancer research, shedding light on the benefit of low-dose CT (LDCT) scanning. LDCT was linked to a 20 percent decrease in lung cancer deaths in both current and former smokers.

The Mallinckrodt Institute of Radiology (MIR) at Washington University School of Medicine in St. Louis has one of the largest thoracic imaging and cardiac radiology services in the country. Our experts interpret about 120,000 chest radiographs, 12,000 chest CTs and performing 250 lung biopsies every year. They have unique expertise in thoracic MRI and are sought globally to speak on MRI of the chest.

Our thoracic radiologists are renowned for their accomplishments in lung cancer research and chest imaging. Our members include past presidents of the North American Society for Cardiovascular Imaging (NASCI), the Society of Thoracic Radiology (STR) and the Society of Advanced Body Imaging (SABI). We have also had 2 members of the Fleischner Society, an esteemed international society dedicated to thoracic disease.

Yearly lung cancer screening: Is it right for me?

Frequently asked questions

Who can get screened for lung cancer?

If you’re 50-80 years old and have a smoking history of 20 pack years or more, you can get screened.

Examples of at least a 20 pack year smoking history:
1 pack per day for 20 years, three-quarters of a pack a day for 30 years or half a pack a day for 40 years. Calculate your pack year history

If you have smoked this amount or more, you may be eligible for lung cancer screening. Even if you quit smoking, you can get screened as long as you quit in the past 15 years

What are the costs of a lung cancer screen?

Costs may differ based on your specific benefit and coverage information, as well as the specific services you receive. Please contact your insurance provider to ask about your expected out-of-pocket costs.

Medicare currently covers the costs of lung cancer screening for eligible patients. Many private insurance companies do as well. In some cases, you may have to pay a portion of the costs.

What if my results are abnormal?

Lung nodules are very common and most are benign, often resulting from past infections or scar tissue. Still, if a nodule is detected during screening, more testing will likely be needed to see if it’s cancerous. The next step is usually a repeat CT scan to see if the nodule has grown. This may take place a few months to a year after the first scan. Based on these results, your doctor may order further imaging tests, like a positron emission tomography (PET) scan. If the nodule has grown or has other concerning features, a biopsy will be needed to confirm a diagnosis.

Your results will be read by our world-class physicians who have expertise in diagnosing and treating lung cancer. Should your results require a follow-up, Siteman Cancer Center’s multidisciplinary team can provide a comprehensive assessment and treatment options.

Are there risks that come with screening?

As with any scan of this kind, you will be exposed to some radiation, which has potential health risks. However, because our team uses a low-dose CT scan, there is less exposure than with traditional lung cancer tests. It’s important to discuss these risks and other risks with your doctor.

What are low-dose CT lung scans?

A low-dose spiral computed tomography (CT) image takes many pictures of your lungs that a specialist scans for cancer. Because LDCT scans are “low-dose,” they use a reduced amount of radiation compared to other CT imaging. During the scan, which takes about a minute, you’ll lie on a table while a technician performs the test. There are no needles used or contrast dyes used.
