AJCC Cancer Staging Manual

The AJCC Cancer Staging Manual is a widely used system that classifies how advanced a cancer is in a person's body. It uses a set of standardized categories—typically labeled as T (tumor size and location), N (lymph node involvement), and M (metastasis or spread to other parts)—to assess the cancer's severity. This staging helps doctors determine treatment options, predict outcomes, and communicate about the disease effectively. The manual is regularly updated, ensuring it reflects the latest research and clinical practices for various types of cancer.
