Medical imaging scans that create detailed images of the body’s internal structures are widely used in medicine. Doctors need them to detect and manage certain types of cancer, assess the extent of ...

For example, low-dose chest CT scans performed for lung cancer screening use lower doses than multi-phase abdominal/pelvic CT scans that are required to stage a person with pancreatic cancer.

Researchers projected CT use in 2023 would lead to more than 100,000 future cancer diagnoses, and if trends continued, may account for 5% of new cases annually in the U.S., according to study ...

Adults, however, may face a greater risk since most scans are performed on them. The most common cancers linked to CT scan exposure include lung, colon, bladder cancer, and leukemia.

May 8, 2025 – If you’ve ever hesitated before getting a CT scan, you’re not alone. A recent study linked 5% of all new cancer cases to radiation exposure from CT scans – a finding that’s ...

The study itself is basically a modeling exercise. The authors took an estimate of the number of CT scans done every year in the U.S., based on research from 2023. Next, they estimated the dose of ...

Based on the number and types of scans people underwent in 2023, the researchers estimated that around 103,000 U.S. cancer diagnoses per year could soon be attributed to CT scan radiation exposure.

New research projects that the tens of millions of CT scans performed in the US in 2023 could result in over 100,000 cases of cancer.

A new study suggests the cancer risk from radiation emitted by the CT machine during a scan could be higher than previously thought — up to 103,000 cases from the 93 million scans performed in 2023.

Especially when you consider that the number of CT scans done in the US has jumped by 30% in just over a decade. In 2023, there were an estimated 93 million CT exams carried out on 62 million people.

In 2023 alone, Americans underwent 93 million CT scans, a figure that researchers say could result in nearly 103,000 new cancer cases – three to four times higher than previous estimates.
