If you recently had a computed tomography (CT) scan that revealed a dark spot, or lung nodule, in your chest, you may be concerned about what that means.
A lung nodule is a small area of dense tissue that is seen in the lungs during lung cancer screenings or imaging tests using computed tomography (CT) scans or X-rays. In most instances, nodules aren’t cancerous. However, because lung cancer is the leading cause of death from cancer in the United States, you should always seek follow-up care to accurately diagnose and monitor any sign of lung nodules.
How are lung nodules detected?
Lung nodules look like a white, round shadow and are commonly found during lung cancer screenings using low-dose CT scans. A low-dose CT scan uses advanced x-ray technology to create a detailed 2D image of your lungs. As a result, lung cancer experts can find and track tiny lung nodules early. Because early detection is your best chance of treating lung cancer, it’s important to get screened as soon as you’re eligible.
Are you eligible for a lung screening?
Lung nodules can also appear on other imaging tests, such as X-rays, used for unrelated purposes. Whether your lung nodule appeared during a lung cancer screening or other imaging tests, it’s unlikely that you experienced any related symptoms.
Are lung nodules cancerous?
Most lung nodules are benign, or non-cancerous. In fact, only 3 or 4 out of 100 lung nodules end up being cancerous, or less than five percent. But, lung nodules should always be further evaluated for cancer, even if they’re small. Because lung cancer treatment is more effective when it’s caught early, monitoring your lung nodule early could save your life.
