A new study suggests that radiation from CT scans may be more cancer-causing than previously thought, with up to 103,000 cases of cancer linked to the 93 million scans performed in 2023. The American College of Radiology has stated that there is no direct link between CT scans and cancer, but warns that medical tests must outweigh risks.
CT scans are widely used to diagnose various medical conditions, providing detailed images of organs, blood vessels, and soft tissues. However, this imaging technology also exposes patients to ionizing radiation, which can increase the risk of cancer.
According to experts, patients should be aware of the radiation risks associated with CT scans but not shy away from the technology, which has been instrumental in declining cancer rates. Dr. Helise Coopersmith, a radiologist at Northwell Health, emphasizes the importance of patients advocating for themselves and asking questions about medical procedures.
The study found that lung cancer and colon cancer were the most common radiation-induced cancers among CT scan patients. The use of CT scans has increased by 30% since 2007, with most cases being unnecessary or low-value imaging. However, advances in technology have led to a significant decrease in radiation doses over the past 15 years.
As medical imaging technologies continue to evolve, it is essential for patients and healthcare professionals to weigh the benefits and risks of each procedure to ensure safe and effective care.
