Computed Tomography Scan
CT Scan A full-body scan can theoretically catch deadly diseases (e.g. cancer) in early stages, which can save lives. However in practice, the benefits may not outweigh the risks. Thus, controversy arises from the use of full-body scans in the screening of patients who have not been diagnosed with a disease, or who do not have symptoms suggestive of a disease. As with any test that screens for disease, the risks of full-body CT scans need to be weighed against the benefit of identifying a treatable disease at an early stage.
