Stomach Cancer Stages

Stomach Cancer Stages

We determine the stage of the stomach cancer based on a number of factors. The most common way to diagnosis and identify stomach cancer stages is a classification system known as the TNM system. The TNM system helps identify stomach cancer stages based on:

  • Size of the tumor
  • The number of lymph nodes involved
  • How far the cancer has spread (metastasized)

Learn more about the TNM system.

Stomach Cancer Staging Tests

Testing to help determine and identify the stages of stomach cancer may include:

After we complete the testing, we can determine the stage of stomach cancer. The classification of different levels of stomach cancer is called "stage grouping." Learn more about stage groupings of stomach cancer.
