Lung cancer screening involves a low dose computed tomography or LDCT scan of a patient's chest to make detailed pictures of the lungs. The exam is painless, non-invasive, and only takes a few minutes. Radiologists examine the images for abnormalities that could indicate cancer.
You must meet certain criteria to be considered for lung cancer screening. LDCT screening is recommended for patients who have an increased risk of developing lung cancer, but who are still in reasonably good health.
There are some minor risks associated with low dose CT screening. For example, not all nodules are lung cancer, and there may be a need for additional tests and procedures. This can cause anxiety for some patients. Discuss the risks and benefits of low dose CT screening with your doctor.
If your screening shows you may have cancer, our multidisciplinary lung cancer team works together to determine which treatments will be most effective for you. Even if your screening is normal, you should still stop smoking. The best way to reduce your risk of developing lung cancer is to quit smoking. Our Courage to Quit smoking cessation program can assist you in taking the right steps toward a smoke free life.
Lung cancer screening can save your life. UChicago Medicine offers lung cancer screening at several locations. Want more information about lung cancer screening? UChicago Medicine is here to help.
Lung cancer is the leading cause of cancer-related deaths in both men and women in the United States. Often, lung cancer will have no symptoms, and by the time patients show signs of the disease, the cancer has progressed to an advanced stage. Proactive measures, such as lung cancer screening, can help diagnose lung cancer in its earlier stages and improve outcomes for patients.
The University of Chicago Medicine lung cancer prevention and treatment team is a collaboration of specialists from oncology, pulmonology, radiology, surgery, pathology and more. These experts work closely together to diagnose and treat each patient. Our goal is to provide the highest level of patient care at every stage of treatment, which includes offering lung cancer screening to qualified patients.
We're proud to be designated a Lung Cancer Screening Center by the American College of Radiologists. This important distinction signifies our program has met rigorous quality standards to provide safe and effective lung cancer screening services.
Lung cancer screening is a method of monitoring patients who are in reasonably good health but have an increased risk of developing lung cancer. Through screening, physicians can identify potential early-stage cancer and begin treatment sooner to reduce the number of patients who progress to end-stage cancer or die from the disease.
Specialists at UChicago Medicine perform a low-dose CT (LDCT) scan of the patient's chest to obtain a detailed image and analyze it for any abnormalities. A LDCT scan is a quick, painless, non-invasive diagnostic test that allows physicians to detect very small abnormalities or nodules in the lungs that could indicate cancer. Additionally, during a low-dose CT, patients are exposed to less radiation during the test, and because it is a CT scan, there are no issues with claustrophobia (unlike with MRI scans).
Typically, screening is performed annually until the patient reaches 77 years old or has ceased smoking for 15 or more years.
Studies have shown that lung cancer screening can reduce the risk of death from lung cancer by 20 percent. Some people develop rapidly growing cancer that can spread before detection, so while it is not a guaranteed solution to preventing fatal lung cancer, it can significantly reduce your risk. In addition to screening, quitting smoking is the best method to reduce your risk for lung cancer.
Several key factors are used to determine whether someone is an ideal candidate for screening, such as age, amount smoked and more. Our criteria for lung cancer screening are as follows:
- Must be between 55 and 77 years of age
- Asymptomatic, not experiencing any signs or symptoms of lung cancer
- Have at least 30 pack years (see below)
- Current smoker or quit within the last 15 years
- Have a written order for LDCT from a qualified health professional following a lung cancer screening counseling that attests to shared decision-making having taken place before the first screening CT
Each candidate must meet all of the criteria above in order to be considered for lung cancer screening.
Pack years are calculated by using the number of years you smoked and the amount of cigarettes smoked each day. Examples of 30 pack years include: 30 years where you smoked one pack a day or 15 years where you smoked two packs a day. Your physician can help you calculate your pack years based on your smoking habits.
The test is designed to screen high-risk patients before they begin to show symptoms of disease, so the largest benefit is the potential to diagnose lung cancer in its early stages and begin treatment immediately in an effort to reduce mortality from the disease.
There are a few risks associated with lung cancer screening that you should consider when deciding if screening is right for you. Possible drawbacks include:
- Additional tests, procedures and follow-up: As abnormalities are discovered during testing, this could lead to additional tests and procedures, such as subsequent scans or biopsies, in order to obtain a definitive diagnosis.
- False negatives/false positives: False negatives occur when the test did not detect an abnormality, but lung cancer is present. This can result in delayed treatment. Alternatively, when physicians believe the results are abnormal, but there is no cancer present, this is called a false positive. Both situations can lead to additional anxiety and distress.
- Diagnosing non-harmful cancer: Physicians cannot be sure which cancers will ultimately become harmful. So, if cancer is found, your doctor will likely recommend treatment. This could theoretically result in treating non-harmful cancer.
You and your physician should discuss the benefits and risks together to decide if lung cancer screening is right for you.
The most effective way to reduce your risk of developing lung cancer is to quit smoking. Experts at UChicago Medicine are committed to your health and can assist you in taking the right steps toward a smoke-free life. Our specially trained clinic staff is available to help you with both behavioral and medical solutions for smoking cessation.

Lung Cancer Screening Finds Cancer Early When Chance of Cure is High
Former long-time smoker Marilyn Nesby,72, was at high risk for developing lung cancer. Fortunately, a screening test called a low-dose CT scan detected cancer at an early stage, before it had spread.Read Nesby's Story
