The amount of radiation would not raise your risk of cancer over your background 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, maintain healthy weight, get HPV vaccine, exercise 30 minutes each day, drink enough water so your urine is mostly colorless. Wish you good health

The radiation risk from modern imaging devices is usually considered minor to trivial, and it would be very rare to result in significant problems. Would urge a perspective that these procedures were important for your health and well-being, and best they were completed to maintain your stability.
