Teenagers should be careful with CT scans

Recently, an international research group reported in a new issue of the British Medical Journal that they analyzed large-scale medical data and found that adolescents receiving CT scans may slightly increase their risk of developing cancer within 10 years. This study reminds doctors to choose CT scans carefully.

Researchers from the University of Melbourne, Australia, and Oxford University in the United Kingdom conducted research on the data of nearly 11 million Australians under the age of 20 and found that out of about 60,000 cases of cancer, 3,150 patients had received it within 10 years. At least one CT scan.

Sara Dabby, an Oxford University professor who participated in the study, pointed out that in terms of the average cancer rate, about 10 out of every 10,000 teenagers will have 39 cancer patients in 10 years, but if all 10,000 teenagers are accepted After a CT scan, the number of people suffering from cancer may increase.

The researchers believe that although CT scans are of great benefit for clinical diagnosis, doctors should use this technique with caution to ensure that it is used only when necessary and that radiation is kept to a minimum. According to reports, with the improvement of technology in recent years, the radiation dose of a single CT scan has gradually declined, but the use of CT scans has continued to increase worldwide.
