A member asked:

Can medullary thyroid carcinoma metastase to the lungs while being undetectable on a thyroid sonogram? or by that time throyd nod are present?

A doctor has provided 1 answer

Theoretically yes: But unlikely. Theoretically all you need is a tiny group of cancer cells at the microscopic level to have the capability to metastasize. However in practice there is almost always a detectable nodule before it metastasizes because the cancer needs to be more advance and aggressive.
