Understandable: Ct scans emit a lot of radiation. It puts you at a slightly greater risk. Get annual physicial exams.

Small to No Risk!: The jury is still out on whether there is a very small cancer risk with low dose medical radiation. The fears associated with the concept of linear non threshold model (assumption that biological damage caused by radiation is directly proportional to the dose) and the idea that any dose, even the smallest, is carcinogenic lack scientific justification! www.Ncbi.Nlm.Nih.Gov/pmc/articles/pmc2663584/.

The concept that cancer induction proceeds similarly after low and high doses and dose rates is inconsistent with biological evidence.

Radiation dose CT chest 5-7mSv; head 1-2mSv; Sinus 0.6mSv. Natural background radiation in US - about 3mSv.So its like living 3 years in US

No such a thing: Do not worry. Population studies do show a risk from ionizing radiation but personal risk is very very small.

Population studies have multiple flaws and are inaccurate! It is unethical to fuel anxiety with debatable hypotheses.

Contrary to prior claims, there was no increase in leukemia or other cancers (except thyroid cancer) after the Chernobyl accident!
