see below: Radiation exposure to head can lead to cancer and it is dose related. Children who have received high dose radiation therapy for head and neck cancer can develop an unrelated form of cancer later on in life. The dosage from ct scan is much lower and the risk is very small. There is no need to be alarmed, do try to avoid more ct scans unless it is absolutely necessary. Mri scan has no radiation.
