Use of transmembrane potentials in the identification of tumour cells

The electrical properties of the cancer cell are useful parameters associated with neoplastic pathophysiological events. Although transmembrane potentials may not serve as inherent tumour markers in many instances, electrophysiological properties are, indeed, very useful in the investigation of malignant cellular proliferation, the influence of malignant disease on normal cell physiology and chemical carcinogenic events and possibly as an in vivo measurement in the cancer patient.
