Title: CT Scans Projected to Result in 100,000 New Cancers in The US
Link: https://science.slashdot.org/story/25/04/14/2...
A new study projects that CT scans conducted in 2023 may result in around
103,000 future cancer cases in the U.S. due to low-dose ionizing radiation.
"[I]t would put CT scans on par with other significant risk factors for
cancer, like alcohol consumption, at least at a population level," reports
ScienceAlert. From the report: At an individual level, the theoretical chance
of developing cancer from a CT scan is thought to be very minimal, if it
exists at all, and patients should not be scared of undergoing these tests if
they are deemed medically necessary. However, the number of CT examinations
performed each year in the US has increased by more than 30 percent since
2007, and researchers suggest that unwarranted tests are exposing the
population to unnecessary radiation. [...] The anonymous data comes from 143
hospitals and outpatient facilities across the US, catalogued in the UCSF
International CT Dose Registry. Using statistics from 2016 to 2022,
researchers predicted 93 million CT examinations were carried out in 2023, on
roughly 62 million patients. Based on the associated radiation risks, the
team estimates that CT scans in 2023 may be tied to 103,000 future cancers.
The findings have been published in JAMA Internal Medicine.
