The article discusses concerns over the increasing use of CT scans and their associated cancer risks. While experts acknowledge the cancer risk linked to these scans, it is relatively small at approximately 0.1% per CT exam. Stephen Duffy and Doreen Lau advocate for the continued use of CT scans when recommended by doctors due to their benefits in diagnosing serious conditions. However, an editorial from Richman and Katz calls for greater awareness among clinicians regarding the necessity of such imaging and suggests considering alternatives like MRIs or ultrasounds to ensure that patient care remains a priority while minimizing health risks.
Stephen Duffy pointed out that while models indicate there's some cancer risk from CT scans, the actual increase is minimal, showing a 0.1% rise in cancer risk per scan.
Doreen Lau emphasized that patients should not hesitate to get scans recommended by their doctors, as the benefits in detecting serious illness usually outweigh the small risks.
Richman and Katz stressed the importance of striking a balance between the risks and benefits of CT scans, suggesting that doctors should consider alternatives when appropriate.
They concluded that addressing the complexity of medical imaging decisions will not have straightforward solutions, advocating education for clinicians on the value of tests.
