Researchers estimated that the use of CT scans in 2023 would cause 102,700 lifetime cancers, including 93,000 cancers in adults and 9700 cancers in children.

So if Americans’ level of CT use and radiation dose from these tests remain constant, CT scans could eventually account for roughly 5% of all new cancer cases every year—a projected level of ...

A new study has set off alarm bells, attributing the overuse of computed tomography – or CT – scans to around 5% of new cancer diagnoses annually. Since 2007, this imaging technology has seen ...

While we can’t say how much a single scan raises any individual’s risk, our figures do show that there’s about one cancer per 50 CTs in girls who get scanned before age 1, for example, and ...

NPR's Ayesha Rascoe asks Dr. Rebecca Smith-Bindman about her research indicating CT scans, which emit radiation, will cause some 100,000 cases of cancer annually.

New research reveals CT scans may cause 5% of U.S. cancer cases annually. Learn the risks, who's most vulnerable, and how to protect yourself.

The NHS carries out around five million CT scans a year for reasons such as assessing internal injuries after an accident and diagnosing conditions like cancer, stroke, or broken bones.

Other experts say the risk of cancer from CT scans is minimal, and these imaging exams are an important diagnostic tool for various cancers. A commonly used computerized scan may slightly increase ...

A new study suggests the cancer risk from radiation emitted by the CT machine during a scan could be higher than previously thought — up to 103,000 cases from the 93 million scans performed in 2023.

As CT scans become increasingly prevalent in U.S. health care, radiation from the often lifesaving imaging technique could come with a steep long-term cost: tens of thousands more cases of cancer, ...

Computed Tomography scans are vital for diagnosis. Recent studies indicate a potential link between CT scans and increased cancer risk. In the United States, millions undergo CT scans annually ...
