Stages, types and grades of oesophageal cancer
The stage of oesophageal cancer tells you how big it is and whether it has spread. There are different ways of staging oesophageal cancer. There is the TNM system and the number staging system. This includes 5 stages - stage 0 (high grade dysplasia) to stage 4.
The type tells you which type of cell the cancer started in and where it began. The grade means how abnormal the cells look under the microscope.

TNM staging for oesophageal cancer
Tumour, node and metastasis (TNM) is the most common staging system doctors use for oesophageal cancer.
High grade dysplasia of the oesophagus
High grade dysplasia means there are severely abnormal cells in the inner lining of the oesophagus.
Stage 1 oesophageal cancer
Stage 1 means your cancer hasn’t spread beyond the thick muscle wall of the oesophagus.
Stage 2 oesophageal cancer
Stage 2 means your cancer might have spread as far as the outer layer covering your oesophagus. It might have also spread into 1 or 2 nearby lymph nodes.
Stage 3 oesophageal cancer
Stage 3 cancer might have spread beyond the outer layer of the oesophagus into nearby tissue. And it might have spread to up to 6 nearby lymph nodes.
Stage 4 oesophageal cancer
Stage 4 means your cancer is advanced. It might have spread into other organs or body structures, lymph nodes or to other body parts, such as your lungs or liver.
