Lung cancer is the leading cause of cancer deaths in the United States and worldwide.
Lung cancer may be detected with a screening test called a low-dose computed tomography (low-dose CT) scan. This screening test can detect lung cancer at early stages.
Low-dose CT scan benefits
- Low-dose CT scans can detect very small nodules (small amounts of extra tissue) in the lung.
- Lung cancer found by this screening is often at an early stage of disease, which is better for treatment and outcomes.
- The screening is painless and non- invasive.
- A low-dose CT scan uses up to 90 percent less ionizing radiation than regular CT scans, and no radiation remains in the body after the scan.
Low-dose CT scan criteria
You may be eligible for an annual low-dose CT scan to screen for lung cancer if ALL of the following apply to you:*
- Are a former or current smokers aged 50-77 (some insurances cover up to age 80)
- Are a former (within the past 15 years) or current smoker who smoked at least one pack per day for 20 years (unless you quit more than 15 years ago)
- No presence of lung cancer symptoms, if so, a non-low dose CT scan may be recommended
*Please talk with your doctor if you are interested in a lung cancer screening exam, have questions about the criteria or would like more information.
