Claim:
1. A non-invasive apparatus for detection of cancer cells in a biological sample, said apparatus comprising: an elongated housing having a distal end and a proximal end; a pair of electrodes mounted at the distal end of the housing, the electrodes comprising an arcuate first electrode and a linear second electrode substantially centered in the arcuate first electrode; an oscillating power source constructed to produce a sinusoidal electric voltage; the oscillating power source electrically connected to said electrodes through a cable from the oscillating power source, through the proximal end of the housing to the electrodes; wherein said electrodes generate a non-uniform sinusoidal electric field between the arcuate and linear electrodes; a light source attached to the distal end of the housing constructed to deliver collimated light to a biological sample being exposed to said non-uniform electric field producing scattered light therefrom; a detector also attached to the distal end of the housing adapted to collect the scattered light; a processor mounted in said housing, the processor processing electrical signals from the detector related to the scattered light to produce an autocorrelation output signal, the processor comparing the autocorrelation output signal with stored autocorrelation signals taken from biological samples containing known cancer cells.
