Identifying Premalignant Lesions & Conditions of Oral Cavity

A morphologically altered tissue which cancer is more likely to occur than its normal counterpart is known as premalignant lesion as described by the World Health Organization in 1978. Premalignant lesions occur prior to malignant lesions but not all malignant lesions arise from premalignant lesions. As not all premalignant lesions transform into cancer, the term “potentially malignant disorders” was advised by the WHO Workshop in 2005.
