Is it true that a fine needle aspiration of a thyroid nodule can lead to metastasis if it is cancerous?

In brief: Not true

i couldn't find where anything like this has been proven.
Careful trained biopsy technique minimizes complications. You should not worry about metastasis from such a procedure, it doesn't happen. You should worry about getting a diagnosis of this nodule, then pursue recommended treatment or surveillance based on results.

In brief: No way to know

probably not. This is a very complex issue.
Autopsy rate of differentiated thyroid cancer is more than 50% in those over 50 years old. This is a cancer that most of us die with not of. DTC is so indolent is hard to believe it could be spread from an FNA. Furthermore, the only alternative to percutaneous biopsy would be surgical excision. This would be much more risky with so many benign nodules

In brief: No

No, there is no evidence that a needle biopsy of a cancerous lesion would cause them to spread.
Needle biopsies are a very common procedure for thyroid and breast nodules, for example.
