Oral Cancer Stages

Oral Cancer Stages

 

Most dentist refer to the TNM System for determining oral cancer. This system was created by the American Joint Committee on Cancer. The first step in staging is to find the TNP

 

T tells how far the main tumor has spread to the surrounding tissue

 

N tells if the lymph nodes near the tumor have been infected with cancer or not

 

M tells if the cancer has spread or metastasized to other organs in the body

The stages of oral cancer

Stage 0 (carcinoma in situ). The cancer is only in the lining of the oral cavity where it first started. It has not spread to nearby lymph nodes or organs in other parts of the body.

 

Stage I.  The cancer is no more than 2 centimeters across. It has not spread to nearby lymph nodes or organs in other parts of the body.

Stage II. The cancer is between 2 cm and 4 cm across. It has not spread to nearby tissues, lymph nodes, or organs in other parts of the body.

 

Stage III. The cancer has not spread to organs in other parts of the body, and 1 of the following is true:

The cancer is more than 4 cm across.

The cancer is any size and has spread to 1 lymph node on the same side of the neck as the primary (first) tumor. The node is no more than 3 cm across and the cancer has not spread to the outside of it.

 

Stage IV. This stage is divided into 3 groups:

 

Stage IVA: The cancer is any size and has spread into nearby tissues, like the bones of the face or jaw, muscles deep in the tongue, the maxillary sinus (the sinuses in the cheeks on both sides of the nose), or the skin on the face. It has not spread to organs in other parts of the body

 

Stage IVB: The cancer is any size and may have spread into nearby tissues, like the bones of the face or jaw, muscles deep in the tongue, the maxillary sinus (the sinuses in the cheeks on both sides of the nose), or the skin on the face.. It has not spread to organs in other parts of the body

 

 

Stage IVC:  The cancer is any size and may have spread into nearby tissues. It may or may not have spread to nearby lymph nodes, but it has spread to organs in other parts of the body, such as the lungs.
