The prognosis of thyroid cancer is still relatively good, and basically the impact on life is still relatively small. If it is a well differentiated papillary carcinoma, it has less impact on life and less impact on other organs, so the prognosis is still relatively good. Frequent X-rays, CT and MRI examinations usually do not lead to thyroid cancer. The amount of radiation from one or several examinations a year is very small. The amount of radiation that you are often exposed to in your living environment is only a little bit more than CT, and its effect is basically not much. Some people say that X-rays and CT will affect the growth and development of children, but doing it several times a year should have no effect on the development of children.
