Risk factors, Diagnosis & Treatment of Oral Cancer
Oral cavity is the most frequent anatomical subsite of upper aero-digestive tract malignancies. Squamous cell carcinoma is the most common histological type and totalizes more than 95% of oral cancer. Main risk factors are tobacco and alcohol exposure and also potentially malignant lesions. These precancerous lesions are a chronic disease of oral mucosa and are responsible for about 20% of oral cancer. The treatment of oral cancer depends on clinical, radiological and endoscopic staging and according to the multidisciplinary tumor board decision. Indeed, tumor staging gives information about loco-regional and metastatic spread. Treatment can include surgery, radiation therapy and chemotherapy
Oral cancer, also known as mouth cancer, may occur in any part of your mouth. It is one of the types of head and neck cancer. It can occur in any region of the oral cavity such as the lip, the floor of the mouth, palate, gingival (gums), or in the tongue . Cancers of the oral cavity may arise from different tissues such as salivary gland, muscle, and blood vessels, or even may be present as metastases from different sites.
