It is the eleventh-most-common cancer in the United States among males while in Canada and Mexico it is the twelfth and thirteenth-most-common cancer respectively. The ASIR for lip and oral cavity cancer among men in Canada and Mexico is 4.2 and 3.1, respectively. [72] Of all the cancers, oral cancer attributes to 3% in males, opposed to 2% in ...
Local anesthesia is not required, but treatment of the entire lip can be quite painful. Cure rates in excess of 96% have been reported. Cure rates in excess of 96% have been reported. Cryosurgery is the treatment of choice for focal areas of actinic cheilitis.
Head and neck cancer is a general term encompassing multiple cancers that can develop in the head and neck region. These include cancers of the mouth, tongue, gums and lips (oral cancer), voice box (), throat (nasopharyngeal, oropharyngeal, [1] hypopharyngeal), salivary glands, nose and sinuses.

Small defects of the upper and lower lip can be closed primarily. For the upper lip, defects of up to 1/4 (25%) of the lip may be closed primarily. For the lower lip, defects of up to 1/3 of the lip may be closed primarily. This means the edges of the defect are simply sutured together in three layers: oral mucosa, muscle, and skin.
There is a very high risk of dysplasia, transformation to squamous cell carcinoma with high mortality (PVL does not transform into verrucous carcinoma, which is a lesion with a good prognosis usually; the similarity of names does not reflect the common origin, but only the resemblance of their appearance).
Oral submucous fibrosis (OSF) is a chronic, complex, premalignant (1% transformation risk) condition of the oral cavity, characterized by juxta-epithelial inflammatory reaction and progressive fibrosis of the submucosal tissues (the lamina propria and deeper connective tissues).
