Medical imaging tests are exposing more of us to potentially cancer-causing radiation. Health mag investigated when you really need that scan – €”and when you should just say no.

A growing number of doctors and medical organizations are worried about the soaring use of medical imaging tests that rely on ionizing radiation. This radiation can damage your cells’ DNA, which may, over time, lead to cancer. The more you’re exposed to, the riskier it is. And thanks to the increase in computed tomography (CT) scans – which typically emit far higher doses of radiation than traditional X-rays or even other imaging tests like mammograms – exposure has risen dramatically.

In 1980, only about 3 million CT scans were performed in the United States. By 2013, that number had skyrocketed to 76 million. Exactly how dangerous are all those zaps? In 2009, National Cancer Institute researchers estimated that the 72 million CT scans performed in 2007 could lead to as many as 29,000 future cases of cancer. ”
