Computed tomography can cause cancer

Can a CT scan damage your health?
It's thought exposure to radiation during CT scans could slightly increase your chances of developing cancer many years later, although this risk is thought to be very small (less than 1 in 2,000)..
Can computed tomography cause cancer?
“There's a risk of developing a tumor if you have a lot of CT scans, but that doesn't usually happen unless you have a very serious life-threatening medical condition,” says Dianna Cody, Ph.
D., professor of Imaging Physics at MD Anderson..
Can medical imaging cause cancer risk?
The amount of radiation during a typical body CT scan (10 mSv) is about the same as the radiation we get every two years from background sources, and the presumed risk of getting a fatal cancer from this amount of radiation is about one in 2,000..
How does radiation cause cancer?
The main initiating event by which radiation damages the cells in the long term is damage to DNA in the cell nucleus.
With well-orchestrated and efficient mechanisms, cells respond to the induced damage and attempt to repair it, but sometimes the damage cannot be repaired or is misrepaired, which may lead to mutations..
Which medical imaging can lead to cancer?
It also comes from various other natural and man-made sources.
X-rays are common medical imaging tests.
They use a type of radiation called ionizing radiation.
This type of radiation can lead to cancer but only in higher doses..
A concern related to CT scanning is radiation exposure.
The thyroid gland is vulnerable to radiation, which can induce thyroid cancer and other benign thyroid diseases, including thyroid nodules, autoimmune diseases, and other noncancer thyroid diseases [6,7].
CT scans play many different roles in the diagnosis and treatment of cancer.
Screening: CT is sometimes used to screen for different types of cancer, such as lung and colorectal cancer.
Diagnosis: Your doctor may order a CT scan to locate and size suspected tumors.
It also comes from various other natural and man-made sources.
X-rays are common medical imaging tests.
They use a type of radiation called ionizing radiation.
This type of radiation can lead to cancer but only in higher doses.
Risk of cancer by number of scans
Participants who received 4 or more CT scans had a higher risk of intracranial tumour (adjusted OR 9.01, 95% CI 2.89–28.11), leukemia (adjusted OR 4.80, 95% CI 1.79–12.84) and non-Hodgkin lymphoma (adjusted OR 6.76, 95% CI 1.91–23.96), but not Hodgkin lymphoma.
Young women who received several chest or cardiac CT scans had the greatest increase in breast cancer risk – about 20%.
While the results of this study sound scary, it's important to keep several things in mind: There are imaging tests that don't use radiation, such as MRI (magnetic resonance imaging) and ultrasound.

Individuals who have had multiple CT scans before the age of 15 were found to have an increased risk of developing leukemia, brain tumors (6), and other cancers (7) in the decade following their first scan.

CT imaging involves the use of x-rays, which are a form of ionizing radiation. Exposure to ionizing radiation is known to increase the risk of cancer. Standard x-ray procedures, such as routine chest x-rays and mammography, use relatively low levels of ionizing radiation.

Radiation During a CT Scan It can damage the DNA in your cells and raise the chance that they'll turn cancerous. These scans expose you to more radiation than other imaging tests, like X-rays and mammograms. For example, one chest CT scan delivers the amount in 100 to 800 X-rays.

The radiation exposure from CT is higher than that from standard x-ray procedures, but the increase in cancer risk from one CT scan is still small.
