You are right to be concerned about radiation exposure. Sometimes these tests are ordered when a test using non-ionizing radiation will do. Always let the ordering and radiology MDs know of your previous exposures. An encouraging thing is that now most CT s use a low-dose technique. Also an MRI can be done instead of a CT. Good luck.

The increase in risk of cancer from these studies is small enough to be not measurable. You can reduce your risk of cancer by adopting healthy habits: Eat a mostly vegetarian diet, avoid alcohol, tobacco and street drugs, avoid excessive exposure to sun, maintain healthy weight, get HPV vaccine, exercise 30 minutes each day, drink enough water so your urine is mostly colorless. Wish you good healt
