Annual CT scans boost cancer risk

Whole body CT scans increases cancer risk. A whole body CT scan delivers a dose of radiation 500 times that of a conventional X-ray and nearly 100 times that of a mammogram. However, the risk of dying of cancer increases by just .08% from one whole body scan. However, that is cumulative over a person's life as they have more of them. Unfortunately, we don't know if overall mortality is harmed. It may be that the gains from the scan may outweigh the costs. We'll keep digging.
