Healthcare providers use staging information to recommend treatment and help predict chances of recovery.
Oral cancers are staged using the TNM system. T stands for the size and location of the primary tumor. N indicates if the tumor has spread to your lymph nodes. M indicates if the tumor has metastasized, or spread to other areas of your body.
The stages for oral cavity cancer are:
