Oral cancer

Squamous cell carcinoma is the major pathologisc type of oral cancer. Adenocarcinomas, sarcomas, and other tumor types also occur. 

The oral cavity is separated into the:

  • tongue, of which the mobile part is the anterior 2/3
  • gums of the upper and lower jaw
  • palate
  • cheek
  • oral vestibule
  • floor of the mouth

Treatment for oral cancer can greatly affect the patient`s speech and swallowing function. The extent of changes will depend on the location and stage of the tumor. In order to reduce the burdens this may cause, thorough information and follow-up is critical.(2).
