Lung cancer is the leading cause of cancer death and the second most common type of cancer in the U.S.[1] One of the reasons lung cancer is so deadly is that symptoms often don’t appear until the disease has reached an advanced stage. Fortunately, low-dose CT lung screening (LDCTLS) has emerged as an effective screening tool to detect early-stage lung cancers, increasing many patients’ chances of survival. While LDCTLS isn’t appropriate for everyone, it has the potential to save lives among high-risk patients.
