CT Scan Risks
Q:
CT Scan Risks

What can too much radiation do to a child? Can it cause death?

A:

Dr. Greene’s Answer:

There is a tiny increased risk of cancer with each tiny increase in radiation exposure. These cancers are not found at the time of the CT scan, but decades later. Since so much time lapses by and since we are exposed to small levels of radiation every day, it is very difficult to determine exactly what the ultimate risk of cancer from a single CT scan may be. It’s not common, but some people do eventually die as a result of an earlier CT scan. Also, the radiation from head CT’s can cause significant eventual damage to the lens of the eye.
