Examination by CT-scan is used to detect hidden diseases in the body. But recent research shows that the X-ray radiation excess of this tool can lead to cancer.

This is based on the findings in the report Archives of Internal Medicine, conducted by Dr. Rita F. Redberg. Researchers urge doctors to limit radiation exposure to patients undergoing CT-Scan.

CT-Scan has become a powerful tool commonly used. We have lowered our threshold value which means that this tool should really be used in patients who need it.

Physicians should be careful in assessing the benefits of each CT-Scan done and inform the patients about the risks of radiation. CT-Scan (computed tomography scan) is a combination of computers and X-ray technology to produce cross-sectional images in detail so that the body can help doctors diagnose and treat disease.

However, new data shows the use of this tool allows the emergence of excessively more harm than good. Types of CT-Scan itself varies from part of the body which will be examined and it dose X-rays vary. For example X-ray radiation dose to the abdomen-pelvis millisieverts ranged between 6-90 and the average usage of 31 millisieverts.

The number of CT-Scan which leads to cancer cases depending on the type of scan, the patient’s age and sex. For example, 1 of 270 women and 1 in 600 men undergoing coronary angiography (to see the heart blockage) at the age of 40 years could be at risk of cancer.

These risks will be two times greater if done at the age of 20 years and the risk is 50 percent lower if the age of 60 years. It is estimated that approximately two-thirds of cancer cases that have occurred in women, because the tendency of the use of this tool is greater in women is about 60 percent.

To ensure safe use, researchers recommended the implementation should focus on the radiation dose is reduced, eliminating unnecessary things done and make medical records to be known how many patients are exposed to X-ray radiation.
