AJCC 8th Edition Staging System

The AJCC 8th Edition Staging System classifies cancer based on its size, spread, and characteristics to help determine prognosis and guide treatment. It uses specific criteria like tumor size (T), lymph node involvement (N), and presence of metastasis (M). Each category is assigned a stage from I (early) to IV (advanced). This system standardizes how doctors assess and communicate cancer extent, ensuring consistent, evidence-based planning across healthcare providers. It combines detailed pathological and clinical information to give an accurate picture of the cancer’s severity and likely course.
