Pathogenicfactors which have been widely reported or popular received are roughly emphasizedas: tobacco, too much alcohol, radiation and long-term stimulation in oral mucosa.Recent years, there are increasing researches focus on the genetic and viral infectionarea of oral and maxillofacial malignant tumor. Mostly have proved the prevalence ofage appear younger trend, and the percentage of female patients gradually increased.Oral and maxillofacial malignant tumor, especially oral cancer and oropharyngealcancer, is easily associated with cervical lymph node metastasis or other body organstransfer.Current researches on second primary or multiple primary oral maxillofacialtumor malignant increase gradually. More and more clinicians have now notice thepresence of two primary tumor, since there is a certain degree of difficulty in curingsecond primary tumor.

For example,71.3%oral cancer samplesshowed squamous cell carcinoma after operation, the ratio of elderly patients (age above55) is62.22%,which constitutes the major part of oral cancer patients, and thesex ratio (male62.96%, female37.04%) remains at the same level as other papershave implied.
