Overview
On biopsy, follicular thyroid cancer is characterized by trabecular, solid, follicular tumor cells that invade tumor capsule or surrounding vascular structures.
Key Biopsy Findings in Follicular Thyroid Cancer
Fine Needle Aspiration Biopsy
- The removal of thyroid tissue using a thin needle. The needle is inserted through the skin into the thyroid. Several tissue samples are removed from different parts of the thyroid.
Surgical Biopsy
- The removal of the thyroid nodule or one lobe of the thyroid during surgery so the cells and tissues can be viewed under a microscope by a pathologist to check for signs of cancer. Because the type of thyroid cancer can be hard to diagnose, patients should ask to have biopsy samples checked by a pathologist who has experience diagnosing thyroid cancer.
