Tumours can appear in the upper aero digestive tract (including the oral cavity) in the soft tissue, in the bone and in the skin of the face and neck.

As the maxillofacial area is formed by various types of tissue, the tumours which develop in it are very heterogeneous (different biological nature and behaviour).
One of the most important tumours is the epidermoid carcinoma. The epidermoid carcinoma of the head and neck is the sixth most frequent cancer in the world. Included in this group is that of the oral cavity, which has a good prognosis if an early diagnosis and treatment is carried out.

The signs and symptoms which can indicate the presence of this disease are: wounds or ulcers which do not heal within a period of 15 days, frequent bleeding in an area of the mouth, white, red or black spots in the mucous or the presence of dry skin or lumps in the mouth or on the neck.

These signs should be evaluated by a specialist because although they are probably caused by a benign or infectious pathology, they could be the indications of cancer of the mouth.

The diagnosis and staging of this pathology must be precise and meticulous to indicate the best treatment in each case.
