IMPORTANCE OF EARLY DETECTION 70% cases are diagnosed in late stages It leads to 5 year survival rate of 57% patients Oral cancer is 90% curable when detected early

Make the room dark & re-examine the oral cavity with vizilite
Intra-oral vital staining With Toluidine blue helps to identify dysplastic and malignant mucous membrane in the oral cavity.
