Overview
Biopsy is the gold standard for diagnosing thyroid cancer. According to the American Joint Committee on Cancer (AJCC), there are 4 stages of follicular thyroid cancer based on the clinical features and findings on imaging. Each stage is assigned a letter and a number that designate the tumor size, number of lymph node regions involved, and metastasis.
