If you had 30 xrays from injury and 2 head ct scans is cancer in your future?

Possibly: Radiation damage of tissue does occur. The younger the person the more frequent there will be a problem. 30 x rays are a large number and certain tissues are more effected than others. In the neck, thyroid tumors are frequently induced in younger people as a result of RT. Minimize any further X rays using MRI if necessary and have physical yearly to check that no growth develops.
