Stage 1

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 1 from the number staging system.

Stage 1

Stage 1 in the number staging system means the cancer is not more than 4 cm in size. It is split into 1A and 1B.

Stage 1A means the cancer is completely inside the pancreas and is smaller than 2 cm in size. There is no cancer in the lymph nodes or other areas of the body.
