At this time, there are no generally accepted recommendations for reducing your risk of thyroid cancer.
Medullary thyroid cancer often is genetically inherited. If anyone in your family has been diagnosed with medullary or other endocrine cancers or if your family is known to carry a mutation (abnormal change) in the RET gene, you may wish to be tested to see if you have this mutation. Medullary thyroid cancers may be part of syndromes that involve other types of endocrine or other cancers, thus a careful family history for cancer is important.
If you carry the RET gene, you may be advised to have your thyroid removed at a very early age to avoid the very high risk of developing medullary thyroid cancer.
