Cancer cells as capacitors: A new approach to the study of cancer staging

Cancer is one of the leading causes of death in the world and estimates indicate that the global cancer burden will continue to grow for the next decades. To date, early diagnosis remains one of the main important factors in improving the effectiveness of therapeutic treatments and reducing the number of deaths. This paper proposes a new approach to the study of cancer in the light of electric currents in the blood. It is a very simple, non-invasive, and low-cost technique that allows real-time observation of cells and tissues. In the method, cancer cells are considered as capacitors with distinctive features due to their altered metabolism and charge changes on their phospholipid surface. When cancer cells intrude into the bloodstream, the blood behaves like a resistance that connects the various capacitors, so the application of an alternating electrical voltage to the system generates displacement currents sensors of a carcinogenic change in the blood. The study opens new perspectives for early detection of cancer based on a simple blood draw.
