Can a simple needle biopsy replace surgery for thyroid cancer testing?

This study looks at whether a fine needle biopsy (a small sample taken with a thin needle) gives the same molecular classification results as a larger surgical sample in people with papillary thyroid cancer. About 130 adults with confirmed or suspected thyroid cancer will provide both sample types, and researchers will compare the results using the Thyroid GuidePx test. The goal is to see if the less invasive needle biopsy can reliably classify the cancer type, potentially reducing the need for surgery in the future.
