Bioelectrical Impedance Analysis of Oral Cancer - A Brief Review

Abstract

World Health Organization has considered the cancer as the 6^th most potential reason for mortality all over the world. Even with all the advancement and development of technology in the field of medicine the cancer remains one of the most fatal diseases all over the world. Among these malignancies Oral Cancers are the most common worldwide. In malignant tissue there is a significant change in the bioimpedance, this change is as a result of increased water and salt content in the cells, change in membrane permeability, altered packing density and orientation of cells. Bioimpedance is the ability of organic tissue to oppose an external electric current. This review provides a brief knowledge about the bioelectrical impedance in oral cancers.
