You risk of cancer is only minimally higher due to CTs than your baseline risk. 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 mostly colorless.

Modern high speed CAT scans provide very low levels of radiation, and do NOT "kill brain cells". Your risk for brain tumors in the future is likely similar to the general population, assuming no genetic history in your family.
