Staging means the size of the cancer and whether it has spread. Doctors can use a number system (stages 1 to 4) or the TNM system to stage your cancer. TNM stands for Tumour, Node, Metastases.
This information is about stage 3 cancer of the pancreas which is part of the number staging system.
In the number staging system, stage 3 means that the cancer has spread outside the pancreas, into the nearby large blood vessels. It may or may not have spread into the lymph nodes. It hasn't spread to other areas of the body.
Stage 3 cancer is called locally advanced cancer.
In TNM staging, this is the same as T4, Any N, M0.
