Many of us are familiar with the life-saving potential of medical imaging, especially when it comes to diagnosing diseases like cancer or assessing bone injuries.
However, recent concerns have surfaced about the very tool that has become a cornerstone in modern medicine.
While this tool have saved countless lives by providing detailed images of the body's internal structures, they may also be playing a role in an alarming rise in cancer cases.
Could this widely-used diagnostic tool actually be contributing to a hidden health crisis?
Let’s take a closer look at this potential danger and what you can do to protect yourself.
CT scans, which use X-rays to capture images, are essential in detecting conditions like cancer, bone injuries, and internal bleeding.
They're also used to guide surgeries and monitor treatment progress.
But here’s the issue: these scans emit radiation.
And while radiation is essential for the imaging process, it’s also a known risk factor for cancer.
The concern is that overuse or over-prescription of these scans might be putting people at an increased risk, especially when radiation doses vary significantly from one machine to another.
The data about CT scans and cancer risk
Research has shown a concerning link between CT scans and cancer.
A study from 2009 revealed that high radiation doses from these scans could be responsible for about 2% of all cancers in the United States—around 30,000 cases a year.
And as the use of CT scans continues to increase, so does the worry that this number will keep climbing.
The problem is compounded by the fact that there’s little regulation around the machines themselves, meaning radiation levels can vary greatly from one hospital to the next.
Dr. Rebecca Smith-Bindman, a professor at the University of California-San Francisco, has spent years studying the risks of CT scans.
She emphasized to NBC News, "We keep doing more and more CTs, and the doses keep going up."
This highlights the importance of regulating radiation levels to minimize unnecessary exposure and potential harm.

Why are CT scans being over-prescribed?
Did you know that there are about 93 million CT scans performed in the US each year?
While many of these scans are necessary, there is growing concern that some are being over-prescribed.
This can be due to financial incentives for hospitals, as CT scans are expensive procedures.
Additionally, doctors may order extra scans out of caution, afraid of missing a diagnosis and facing legal repercussions.

The public health concern: Radiation exposure
We are all exposed to small amounts of radiation daily—from natural sources like sunlight to activities such as flying.
But the radiation from CT scans is much higher. For instance, a roundtrip flight from New York to Tokyo exposes a person to about 0.19 millisieverts (mSv) of radiation.
In comparison, an abdominal and pelvic CT scan can expose someone to up to 31 mSv.
While a single scan may not carry a huge risk, the cumulative effect over time can add up and increase the overall cancer risk.
A 2007 study published in The New England Journal of Medicine estimated that 1.5 to 2% of all cancers in the US could be attributed to radiation from CT scans.
Another study from 2009 found that radiation exposure from CT scans varied widely, with a 13-fold difference in radiation doses between the highest and lowest doses for the same type of scan.
This variability only underscores the need for greater standardization in CT scan procedures.

New regulations: What’s being done to protect you?
To address these concerns, new Medicare regulations will require hospitals and imaging centers to collect and share information about the radiation emitted by their scanners.
This rule is aimed at ensuring that radiation levels are consistent and appropriate for each scan.
If medical providers don’t comply with these new standards by 2027, they could face fines.
These regulations are a step in the right direction, but it will take time before they are fully implemented and show a measurable impact on reducing cancer risk.

What can you do to protect yourself?
As a patient, it’s important to take an active role in your healthcare decisions. Here are some simple steps to help protect yourself from unnecessary radiation exposure:
- Ask questions: Before undergoing a CT scan, ask your doctor about the necessity of the test and whether there are alternatives that use less or no radiation.
- Get a second opinion: If you’re unsure about the recommendation for a CT scan, consider seeking advice from another doctor.
- Stay informed: Keep up with the latest information and guidelines regarding medical imaging and radiation exposure.
- Discuss your medical history: Inform your doctor about any previous scans or radiation exposure, as this could influence the decision on whether you need another CT scan.
By being proactive and informed, you can make better decisions about your healthcare and reduce the potential risks associated with CT scans. Stay safe and always advocate for your health!
