How does medullary carcinoma start?
Medullary thyroid cancer starts as a growth of abnormal cancer cells within the thyroid. These special cells are the parafollicular C cells. In the hereditary form of medullary thyroid cancer, the growth of these cells is due to a mutation in the RET gene which was inherited.
