Summary

This study is for people who have or might have a thyroid nodule or thyroid cancer. Researchers want to learn more about how to diagnose and treat these conditions. Participants will have standard medical tests like blood draws and scans, plus some extra research tests. The goal is to better understand thyroid disorders and improve future care.

What this could lead to
If successful, this could lead to better ways to diagnose and monitor thyroid nodules and thyroid cancer.
What could go wrong
