CT scans or cat scans are widely used to get internal images of the body and to diagnose dangerous treatment conditions – but they can create a hidden risk.
The University of California – A new survey from San Francisco has shown that scans (mathematics tomography) scans may be responsible for 5% for the diagnosis of all cancer every year, in a press release.
“Although some uncertainty exists, it does not significantly affect the original conclusion: a small but meaningful percentage of cancer is associated with CT scan and this number can be reduced,” the first author Rebecca Smith-Bindman, MD, a UCSF radiologist and professor, told Fox News Digital.
5 Cancer type where screening saves maximum life
Researchers estimate that exposure to ionizing radiation from CT scans is comparable to other significant risk factors, such as taking alcohol and excess body weight.

To predict how many future cancers can occur from the current CT scan, researchers have updated the previous analysis of 2023 data related to the scan, scan type and radiation dose, according to Smith-Bindman.
“We have used a good-illegal model to estimate the risk of cancer and conducted the sensitivity analysis to ensure our search view,” he said.
“It is a modeling study, which means our decisions depend on the accuracy of the information used” “
Normal cancer type can be detected with new blood tests
On the basis of review, researchers have assumed that about 103,000 future cancer will occur due to CT scans edited in the United States 2023, the maximum number of cases affect adults between 50 and 69 years of age.
The risk of individual cancer for children and children is maximum, children under the age of 1 are 10 times the chances of developing the disease compared to others.
Smith-Bindman states that adults, however, are responsible for most scans, which are the burden of overall cancer.
“City doses are sometimes more than needed” ”
According to the survey, the most common cancer resulting in city radiation includes lung cancer, colon cancer, leukemia and breast cancer.
The survey, published on April 8, was funded by the National Health Institutes.
“If City is clearly indicated, the facilities are much higher than the risk,” the researcher says. (Estock)
“In many cases, City is the most appropriate test for achieving a quick and accurate diagnosis,” Smith-Bindman told Fox News Digital.
“However, the use of the city continues to grow, which is known as ‘low-value scanning’, which is an increase in imaging performed without the cause of an equitable treatment.”

Based on the search, researchers suggest avoiding unnecessary CT scans to avoid potential damage.
Another risk reducing method is to reduce the radiation dose for a scan.
“City doses are sometimes more than needed, so patients are encouraged to use their healthcare or technicians to use the minimum potential dose for their scan,” Smith-Bindman suggested.

In the end, the researcher said that patients should not be informed about the need for CT scan with their healthcare suppliers and alternative imaging options such as ultrasound or MRI – whether they could be more suitable.
“If City is clearly indicated, the benefits are much higher than the risk,” he said. “But if it doesn’t happen then the scan is best to avoid perfect” “”
“Good patient can be less in terms of care” ”
Dr. Nicole Safia, a board-respected radiologist and Fox News Medical contributor, was not involved in the study but commented on the risks and benefits of CT scans.
He told Fox News Digital, “I have long suggested for the use of medical imaging justice, often mention that good patients can be less in care.”
“Recent research means that many people in the treatment community that connecting the ionizing radiation with the increased risk of cancer from CT scan refers to what has been understood over the years: imaging is a powerful diagnostic equipment, not at risk.”

Safia said that the research could even underestimate the total number of cancers responsible for medical imaging.
“Long delay in many cases of treatment interfering-induced cancer, complex interplays of contribution causes, and they could be strangers due to the image-directed methods, X-rays and other forms of treatment radiation from this study,” he mentioned, “he mentioned.

“Such imaging use and treatment interventions grow – especially in the younger population – the exposure of lifetime growing radiation becomes increasingly important considerations.”
It was said that Safia went ahead, CT scans and other medical imaging methods – “fast and cheap” – saved lives every day.

“The original is balanced. Physicians must be aware of the benefits against risk and if appropriate like ultrasound or MRI, it should always be searched for alternative methods, which do not use ionizing radiation,” he said.
It is necessary to make a informed decision for both physicians and patients, the doctor said.

“We must refine our protocols, limit unnecessary imaging and make sure we are using the lowest possible dose without compromising the diagnostic quality,” said Safia.
“This is not a call to avoid CT scans – it’s a call to use them wisely.”
