Thyroid Cancer Stages: Understanding the Progression (Stages I-IV)

Stage I: The cancer is confined to the thyroid gland.

Stage II: The cancer has spread to nearby tissues, such as the lymph nodes in the neck.

Stage III: The cancer has spread to other parts of the body, such as the lungs, bones, or brain.

Stage IV: The cancer is recurrent, meaning it has come back after treatment.
