Pancreatic cancer is classified into stages 0 through IV to indicate to what extent the cancer has invaded the pancreas and whether it has infiltrated nearby tissues, other organs, or the lymph nodes (small organs that produce immune system cells that circulate throughout the body).
- Stage 0: Abnormal cells are growing in the inner layer of the affected organ. These cells may develop into cancer. This stage is also called carcinoma in situ.
- Stage I: The cancer is confined to the pancreas.
- Stage II: The cancer has spread to nearby organs or lymph nodes.
- Stage III: The cancer has spread to major blood vessels near the pancreas and may have spread to adjacent lymph nodes.
- Stage IV: Cancer has spread to organs far away from the pancreas, such as the liver, lung, or peritoneal cavity. It may have also spread to lymph nodes or blood vessels near the pancreas.
