Stomach cancer
Tumour, node and metastasis (TNM) staging is the most common way that doctors stage stomach cancer.
High grade dysplasia means there are severely abnormal cells in the inner lining of the stomach.
Stage 1 stomach cancer usually means that your cancer hasn’t spread beyond the thick muscle in the stomach wall.
Stage 2 stomach cancer means your cancer has spread into or through the inner, supportive or muscle layer of the stomach. It might have also spread into nearby lymph nodes.
Stage 3 stomach cancer means your cancer might have grown into or through the inner, supportive, muscle or outer layer of the stomach. It might have spread to nearby lymph nodes.
Stage 4 stomach cancer has spread into nearby organs or body structures, or it has spread to distant body parts.
