Lung cancer kills more people than any other cancer in the world and in Australia. This is often because lung cancer symptoms are not always apparent until the cancer is advanced and difficult to cure. As with breast and bowel cancer, screening (looking for lung cancer in people who do not have any symptoms) can reduce mortality as cancers can be detected at an earlier stage when it is easier to treat. Lung cancer screening is done using non-contrast computed tomography (CT) scans.
The International Lung Screen Trial (ILST) is building on previous studies to test ways to increase the effectiveness of lung screening and is recruiting healthy, asymptomatic volunteers at high risk of lung cancer in Australia, Canada and Hong Kong.
