Individuals exposed to the radiation emanating from a CT scan are at an elevated risk of developing thyroid cancer and leukemia, a new study says. Moreover, researchers concluded that patients receiving CT scans had in general marked increases in the risk of developing thyroid cancer and leukemia, especially in female patients and patients younger than 45. The study conducted from a National Health Insurance dataset in Taiwan between 2000 and 2013 has highlighted. Results showed that patients who developed thyroid cancer and leukemia had a significantly higher likelihood of having received CT scans. In studies that combined patients across age groups, exposure to medical CT scans was not associated with increased risk for non-Hodgkin lymphoma. In older patients, the association between exposures to CT scans and non-Hodgkin lymphoma was not evident.
