What Is Oral Cancer?
Oral cancer is a malignancy arising from any part of the oral cavity. This can be an ulcer (sore) or a growth.
Oral cancer includes:
- Cancer of the tongue
- Floor of mouth
- Buccal mucosa (inner lining of the cheek)
- Hard palate
- Retromolar trigone (the area between the back parts of the upper and lower gums)
- Upper and lower gingiva (gums)
Cancer of the lip is frequently also included in the category of oral cancers.
All oral cavity cancers have a tendency to metastasize (spread) to the lymph nodes of the neck. Generally, cancer spreading outside the head and neck is uncommon unless the cancer is quite advanced.
