Lip and oral cancer staging

For oral cancer, Stages I and II are combined and classified as early cancer. Stages III and IV are classified as advanced cancer. Here are the details of each class:

Early cancer

Stage I or II oral cancer is usually a small tumor (smaller than a walnut), and no cancer cells are found in the lymph nodes.

Advanced cancer

Stage III or IV oral cancer is usually a large tumor (as big as a lime). The cancer may have invaded nearby tissues or spread to lymph nodes or other parts of the body.
