A new study says that people who are exposed to radiation from a CT scan are at high risk for the development of thyroid cancer and leukemia.
Researchers also found that the risk of developing thyroid cancer and leukemia, in particular in women and patients under 45, was significantly higher among patients receiving CT scans.
“Our study found that CT scans are associated with an increased risk of thyroid cancer and leukemia in adults in all ages and with non-Hodgkin lymphoma in young adults,” said Yu-Hsuan Joni Shao, one of the paper’s authors.
Thus, the study conducted by a National Health Insurance dataset in Taiwan between 2000 and 2013 has highlighted. Also, this followed 22,853 cases of thyroid cancer, 13,040 cases of leukemia. In like manner, 20,157 cases of non-Hodgkin lymphoma, published in the journal JNCI Cancer Spectrum.
Further, researchers consulted data from the National Health Insurance program to study demographic and medical information on disease diagnoses, procedures, and drug prescriptions, and the enrollment profiles of all patients.
CT Scan Increases Risk of Non-Hodgkin lymphoma
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 increased the risk of non-Hodgkin lymphoma.
Nevertheless, the non-Hodgkin lymphoma risk associated with CT scans has doubled in patients between the ages of 36 and 45.
In older patients, the association between exposures to CT scans and non-Hodgkin lymphoma was not evident.
“The risk is stronger in patients who have higher cumulative doses from multiple scans. The increased numbers of people undergoing CT scans have become a public health issue,” Shao explained.
