Stage III head and neck cancer
At stage III, the tumor fits one of the following criteria:
- It is larger than 4 cm across, and no cancer cells are present in nearby structures, lymph nodes or distant sites (e.g., T3, N0, M0).
- It is any size but has not grown into nearby structures or distant sites. However, cancer cells are present in one lymph node, which is located on the same side of the head or neck as the primary tumor and is smaller than 3 cm across (e.g., T1-3, N1, M0).
