A new electronic instrument allows for very easy in vivo cancer detection. It is sufficient, indeed, to bring a handy probe close to the organ that should be tested, without even touching the body. The probe contains batteries, an electronic circuit and a small antenna, emitting a very weak EM wave that has several frequency components (at 450, 900 and 1350 MHz, for instance). Their intensities are displayed as spectral lines on the screen of a spectrum analyser, intercepting the wave about 2 m away from the probe. The height of one or several of these lines can be strongly reduced, however, according to the pathological state of the tested biological tissue. We show that these properties result from the fact that malignant and normal tissues have different electric properties and that these modifications are efficiently revealed through non-linear resonance interaction.
