There are altogether five stages of pancreatic cancer. Stage 0 (also called carcinoma in situ) is the earliest stage. Then it ranges from Stage I to Stage IV. The lower the number is, the less the cancer has spread.
At this stage the cancer is confined to the top layers of pancreatic duct cells. It has not spread to outside of the pancreas and other distant sites.
The tumor at Stage I is confined to the pancreas, growing bigger that Stage 0 tumor. It is usually no bigger than 4cm.
The cancer is still confined to the pancreas but it has spread to nearby lymph nodes. However, it has not spread to distant sites.
The cancer is still confined to the pancreas but it has spread to 4 or more nearby lymph nodes. Or it may have spread to nearby major vessels. In this stage, the cancer has not spread to distant sites.
The cancer has spread to distant sites such as the liver, lungs or bones. It can be any size and might or might not have spread to nearby lymph nodes.
