RELAX, YOU ARE NOT GOING TO GET CANCER FROM A CT SCAN, AND THE INJECTED DYE IS ALSO SAFE IF YOU ARE NOT ALLERGIC. Recommend you screen what you read online, and find your answers here on the HealthTap site.

Two CTs will not raise your risk of cancer to any measurable extent over your baseline risk. The contrasts used in CT are not radioactive. 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, get HPV vaccine, exercise 30 minutes each day, drink enough water so your urine is colorless.
