Primary Tumor (T)
T4  Tumor invades adjacent structures (e.g.,
    (lip) through cortical bone, inferior alveolar
          nerve, floor of mouth, skin of face)
    (oral cavity) through cortical bone, into deep [extrinsic]
                  muscle of tongue, maxillary sinus, skin.
                  Superficial erosion alone of bone/tooth
                  socket by gingival primary is not sufficient
                  to classify as T4)

TX  Primary tumor cannot be assessed
T0  No evidence of primary tumor
Tis Carcinoma 'in situ'
T1  Tumor 2 cm or less in greatest dimension
T2  Tumor more than 2 cm but not more than 4
      cm in greatest dimension
