CT Scans Projected to Result in 100,000 New Cancers in The US
A recent study reveals that approximately 103,000 new cancer cases in the United States could be linked to CT scans performed in 2023, primarily due to low-dose ionising radiation. This alarming figure positions CT scans alongside other major risk factors for cancer, such as alcohol consumption, at a population level. While the individual risk of developing cancer from a CT scan is deemed minimal, researchers highlight concerns over the rising number of unnecessary scans contributing to increased radiation exposure.
The data, drawn from 143 healthcare institutions, indicates that an estimated 93 million CT examinations were conducted in 2023 on around 62 million patients. The findings, published in JAMA Internal Medicine, underscore the potential dangers associated with the escalating use of CT scans in medical diagnostics.
Key Points
- CT scans in 2023 may lead to approximately 103,000 new cancer cases in the US due to ionising radiation exposure.
- Individual risk of cancer from a single CT scan is considered very low, but cumulative exposure raises concerns.
- CT examinations have increased by over 30% since 2007, with many tests potentially being unnecessary.
- The study used data from 143 facilities and estimated 93 million scans were performed on roughly 62 million patients in 2023.
- The findings were published in JAMA Internal Medicine, highlighting the need for cautious use of imaging technology.
Why should I read this?
This article exposes a critical public health concern regarding the implications of CT scans and their contribution to cancer rates. Readers interested in healthcare, medical diagnostics, or public health policies may find the study’s findings particularly relevant as they highlight the balance between necessary medical imaging and the risks associated with excessive radiation exposure.
