The nationally-ranked lung cancer program at Duke uses the latest digital imaging technology to screen for and detect lung cancer at the earliest possible stage. We use the most advanced diagnostic screening tool, low-dose CT scans. Low-dose CT is a fast, safe, noninvasive study that collects 3-D images of the lungs. These 3-D images show early-stage lung cancers that may be too small to be detected by a traditional chest X-ray. We offer appointments for lung cancer screening at convenient locations in Raleigh and Durham.
