CT scan or scanning cats are widely used to obtain internal images of the body and diagnose dangerous medical conditions – but they could be a hidden risk.
New Study from the University of California – San Francisco revealed that CT scan (computer tomography) could be responsible for 5% of all of all Cancer diagnosis Every year, according to a statement to the public.
“Although some uncertainty exists, it does not affect the basic conclusion: a small but meaningful percentage of cancer is associated with CT scanning, and that number can be reduced,” said the first Rebecca Smith-Bindman, MD, UCSF radiologist and professor, for Fox News Digital.
5 types of cancer where projections are saving the most lives
Researchers’ assessments show that exposure to ionizing radiation from CT scan is comparable to other significant risk factors such as Alcohol consumption and excess body weight.

In order to predict how many future cancers can be the result of current CT scanning, researchers updated the previous data analysis 2023. On the quantities of scanning, types of scanning and doses of radiation, according to Smith-bindman, Dr. med.
“We used a well -validated model to evaluate Risk of cancer And she spent analysis of sensitivity to confirm the robustness of our findings, “she said.
“This is a modeling study, which means that our conclusions depend on the accuracy of the information used.”
The usual cancer type can be detected by a new blood test
Based on the examination, researchers estimate that about 103,000 future cancer will be caused by CT scanning performed in 2023 in the US, and the largest number of cases affecting adults between the ages of 50 and 69.
An individual risk of cancer is the largest for babies and childrenWith babies under 1 year old 10 times more likely to develop a disease compared to others in the study.
Adults, however, represent most of the scanning, which drives the overall burden of cancer, Smith-Bindman noted.
“CT doses are sometimes bigger than necessary.”
According to the study, the most common types of cancer arising from CT radiation lung cancerColon cancer, leukemia and breast cancer.
The study, which was published on April 14 in internal medicine, received funds from the National Health Institutes.
“If CT is clearly indicated, it uses far outweigh the risks,” the researcher said. (East)
“In many cases, the CT is the most appropriate test to achieve fast and accurate diagnoses,” Smith-Bindman told Fox News Digital.
“However, the use of CT continues to grow, including an increase in the recording performed without a justified medical reason-is often called” low value scanning. ”

Based on findings, researchers recommend avoiding unnecessary CT scanning to avoid potential damage.
Another approach to reducing the risk is to reduce the radiation dose by scanning.
“CT doses are sometimes bigger than necessary, so patients are encouraged to ask their health services providers Or technologists use the lowest possible dose for their scanning, “Smith-Bindman advised.

Finally, the researcher said, patients should have informed the conversations with their health care providers about the need for CT scan and whether alternative recording options – such as ultrasound or MRI – could be more appropriate.
“If CT is clearly indicated, it uses far outweigh the risks,” she said. “But if not, it is best to avoid scanning.”
“Less may be more when it comes to good patient care.”
Dr. Nicole Saphier, a certification of the Committee certificate and a medical associate of Fox News, was not involved in the studio, but commented on the risks and benefits of CT scanning.
“I have long advocated a reasonable use of medical recording, often stating that less can be more when it comes to Patient care“She told Fox News Digital.

“A recent study that connects ionizing radiation with CT scan with increased risk of cancer emphasizes what many in the Medical Community have understood for years: although recording is a powerful diagnostic tool, is not risk without risk.”

Saphier said the study could even underestimate the total number of cancer that can be attributed to medical recording.
“Many cases of cancer caused by medical interventions may be unrecognized because of long delays, a complex interaction of factor that contributes and the facts that they have omitted radiation from Procedures guided by picturesX-rays and other forms of medical radiation from this study, “she noticed.

“As the use of paintings and medical interventions is still growing – especially in the younger population – cumulative radiation exposure becomes more important during life.”
Accordingly, Saphier continued, CT scanning and other medical shoot modalities – which are “fast and cheap” – save lives every day.

“It is a key balance. Doctors must remain awake in the use of risk benefits and should always explore alternative modalities when appropriate, such as ultrasound or MRI, which do not use ionizing radiation.”
Informed decision -making is necessary for both clinicians and patientsAccording to the doctor.

“We need to continue to improve our protocols, limit unnecessary recording and ensure that we use the lowest possible doses without disrupting diagnostic quality,” Saphier concluded.
“This is not a call to avoid CT scan – it’s an invitation to wisely use them.”
