Up to 70% of oral cancers are preceded by premalignant oral lesions, such as persistent red or white patches in the mouth. Survival rates for oral cancer can be improved through early detection. It is therefore essential that oral health professionals such as dentists, dental hygienists, dental therapists, and oral health therapists understand the importance of conducting a thorough oral screening examination for malignant and potentially malignant lesions as part of their routine clinical assessments, even in younger populations considered at lower risk for oral cancer. Key features of the book include: laser treatment techniques ,human genome sequencing, early detection and multidisciplinary approach ,management strategies and mechanisms of proliferation and energy metabolism in oral cancer.
