Esophageal And Stomach Cancer – Types & Stages

Esophageal And Stomach Cancer: Types & Stages

The American Joint Committee on Cancer (AJCC) developed the TNM staging system for evaluating the extent and spread of stomach cancer. The staging process is a basis for selecting treatment options and helping doctors communicate potential outcomes (prognosis). The TNM system considers three important factors:

  • T ­- Describes the size and growth of the primary stomach tumor.
  • N- ­Provides information about stomach cancer found in regional lymph nodes.
  • M­- Indicates whether the cancer has metastasized, or spread to other areas.

Each of these categories are rated on a numbered scale, the higher the number indicates increased severity. These categories are then grouped into stomach cancer stages from 0­IV.
