“The stage of a cancer describes how much cancer is in the body. It helps determine how serious the cancer is and how best to treat it. The staging system used most often for pancreatic cancer is the AJCC (American Joint Committee on Cancer) TNM system, which is based on 3 key pieces of information: 1-extent of the tumor (T) 2- spread to nearby lymph nodes (N) 3- The spread (metastasized) to distant sites (M).”
