The most recent version of the American Cancer Society (ACS) lung cancer screening guideline (from 2018) is being taken down while we review new scientific evidence to be included in the next update. But this kind of testing is for diagnosis and is not the same as screening.) American Cancer Society lung cancer screening guideline (People who already have symptoms that might be from lung cancer may need tests such as CT scans to find the cause, which in some cases may be cancer. If you have symptoms that could be from lung cancer, see your doctor right away. Even when lung cancer does cause symptoms, many people may mistake them for other problems, such as an infection or long-term effects from smoking. Usually symptoms of lung cancer don't appear until the disease is already at an advanced stage. If a person has lung cancer but doesn't have any symptoms, this usually means there's a chance to detect the disease early. Lung cancer screening is recommended for certain people who smoke or used to smoke, but who don't have any signs or symptoms. If lung cancer is found at an earlier stage, when it is small and before it has spread, it is more likely to be treated successfully. It’s also the leading cause of death from cancer. In the United States, lung cancer is the second most common cancer. Reasons to screen people at higher risk for lung cancer For these people, getting yearly LDCT scans before symptoms start helps lower the risk of dying from lung cancer. ![]() Research has shown that unlike chest x-rays, yearly LDCT scans to screen people at higher risk of lung cancer can save lives. LDCT scans can help find abnormal areas in the lungs that may be cancer. In recent years, a test known as a low-dose CT (LDCT) scan has been studied in people at higher risk of getting lung cancer (mainly because they smoke or used to smoke). Regular chest x-rays have been studied as a screening test for people at higher risk for lung cancer, but they haven't been shown to help most people live longer, and therefore they aren't recommended for lung cancer screening. Screening is the use of tests or exams to find a disease in people who don’t have symptoms.
