The risk for cancer from two CT scans is quite low. Certainly you would not undertake that risk for a frivolous reason, but most CT scans are done to evaluate for a more serious problem, usually MUCH more serious than the risk of cancer. CT scans can help direct treatment in people with cancer and thus prolong their lives. Consider: All people crossing the street risk being run over by a bus.

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.
