Excessive CT scan can cause cancer

Excessive CT scan can cause cancer

For many patients, it is a common practice to diagnose the condition through CT scan. However, Australian researchers recently reminded patients that the radiation dose produced by CT scans far exceeds that of conventional X-ray examinations, and that excessive use can easily lead to cancer.

The Australian Medical Regulatory Authority issued a communiqué a few days ago stating that the agency attaches great importance to the unreasonable use of CT scans with cancer detectors, and relevant medical radiologists also urge doctors not to abuse CT scans to check the condition. Australian medical researchers believe that more than 400 new cancer cases in Australia each year are caused by the frequent use of CT scans for diagnosis. Therefore, doctors are advised not to use CT scans as the first choice for diagnosis of diseases such as back pain.

A survey of medical students in Perth, Australia showed that more than half of senior students underestimated the radiation dose produced by CT scans. It is reported that the number of people undergoing CT scans in Australia is currently increasing at an average annual rate of 12%.
