The benchmark study
A November 2010 study from the National Lung Cancer Screening Trial (NLST) found:
- 20 percent reduction in lung cancer mortality among current or former heavy smokers when cancer was detected by a low-dose CT scan versus a chest x-ray.
- Of those cancers detected during the trial, 40 percent were found at an early and treatable stage.
The NLST was performed by the American College of Radiology Imaging Network and the National Cancer Institute.
NCH became one of the first hospitals in the Chicago area to launch an Early Lung Cancer Screening program in early 2011.
How to determine if you are at high risk
Not everyone should be screened for lung cancer. It is important to only screen individuals at increased risk for lung cancer.
The single most important risk factor for lung cancer is cigarette smoking.
Tobacco use accounts for almost 90 percent of all lung cancers. If you have ever smoked, you have an increased chance of developing lung cancer. The longer you smoke and the more packs you have smoked, the greater the risk of developing cancer.
Are you or a loved one eligible for this screening?
You must meet all of the following criteria as a high-risk smoker to be eligible for an Early Lung Cancer Screening at NCH:
- You are between 55 and 80 years old and have smoked, on average, one pack a day for 30 years or the equivalent, e.g., 2 packs a day for 15 years.
- You are currently smoking or have quit within the past 15 years.
- You have no signs or symptoms of lung cancer.
