Majority of them are associated with tobacco chewing and usually preceded by premalignant lesions.On an average, about 1% of oral lesions transform into cancer annually.15 to 20% of dysplastic lesions develop into carcinoma.One of the primary reasons for the poor prognosis is the lack of significant and unique molecular tumor markers to assess risk and prognosis.
