Detection of field alterations using useful tools for oral squamous cell carcinoma
It is known that a region of epithelial dysplasia cannot easily be distinguished macroscopically from normal looking area surrounding early oral squamous cell carcinoma (OSCC). In 1953, Slaughter emphasized field cancerization and the importance of examining the fields surrounding OSCC. Since 1997,...
