CT scans found to raise cancer risk

If you've ever received a CT scan at a hospital or medical facility, you mayor may not realize that a huge dose of radiation is being sent through your entire body. That's how the image is formed -- since soft tissue passes radiation right through while hard structures like bone don't.

A new report says that millions of Americans (and in particular, children) are seeing needless radiation amounts from so many CT scans that are intended to diagnose medical problems but could be the cause of some of them.

Although the risk from a single CT scan is small according to the report, but in a few decades, the report estimated that two percent of cancer cases may be due to CT scans being performed today.
