Once a person’s T, N, and M categories have been determined, this information is combined in a process called stage grouping to assign an overall stage. The earliest stage stomach cancers are called stage 0 (carcinoma in situ), and then range from stages I (1) through IV (4). The lower the number, the less the cancer has spread.
After someone is diagnosed with stomach cancer (gastric cancer), doctors will do exams and tests to help determine if it has spread, and if so, how far. This process is called staging. The stage of a cancer describes the extent of the cancer in the body.
Using the TNM system, the “T” plus a letter or number (0 to 4) is used to describe the how far the tumor has grown into the stomach wall. Tumor size is measured in centimeters (cm). A centimeter is roughly equal to the width of a standard pen or pencil. Stage may also be divided into smaller groups that help describe the tumor in even more detail.
