Overview

According to the American Joint Committee on Cancer (AJCC) there are 4 stages of papillary 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 involved lymph node regions, and metastasis.

Staging

  • According to the American Joint Committee on Cancer (AJCC) there are 4 stages of papillary thyroid cancer based on the clinical features and findings on imaging.[1]
  • Each stage is assigned a letter and a number that designate the tumor size, number of involved lymph node regions, and metastasis.
