Does DNA repair itself after CT scan?
After the scans, the research did show an increase in DNA damage in cells, as well as cell death. There was also increased expression of genes involved in the repair or death of cells, the study found.

What are the dangers of X-rays and CT scans?
X-rays and CT scans expose the body to ionizing radiation, which increases the risk of cancer by damaging genes. It is speculated that CT scans being done now will result in as many as two percent of the fatal cancers that will occur in the next 10 to 20 years. Another danger is that indiscriminate use…
Can low doses of radiation from CT scan cause cancer?
Some scientists believe that low doses of radiation do not increase the risk of developing cancer at all, but this is a minority view.” Any medical procedure has some risk attached to it. With CT, as with any other X-ray based examination, the guiding principal is to be exposed to it as little as possible.
How much does recurrent CT imaging increase cancer risk?
“We found that while most patients accrue small cumulative cancer risks, 7\% of the patients in our study had enough recurrent CT imaging to raise their estimated cancer risk by 1\% or more above baseline levels,” says lead researcher Aaron Sodickson, MD, PhD.
