An electrical impedance index to distinguish between normal and cancerous tissues

Bioimpedance measurements have previously shown that cancerous tissues in m any cases have a higher characteristic frequency than normal tissues. This paper tries to find an index which is sensitive to variation in the charact eristic frequency but is independent of the impedance value itself: Calcula ted indexes from several publications in most cases shout values larger tha n one for cancerous tissues and less than one for normal tissues.
