Diagnostic method and sensor device for detecting the location and/or character of lesions in body tissues. Electrodes of different substances are put onto or into a tissue being tested, the electrodes are nearly short-circuited over a measuring device, and the current flowing through the terminals of the electrodes is measured. The measured value of the current is then compared with a control value measured in the same way on a piece of sound tissue. One embodiment of a sensor device that can be applied for the performance of the method comprises a pair of electrodes, made of different materials so as to have different contact potentials, the electrodes being coupled to an electric measuring instrument, e.g. an ammeter, one of the electrodes being a metal tube such as a medical syringe, whereas the other electrode is enveloped by an insulating material and fixed inside the metal tube. The other electrode can be made of magnesium, and its active surface is preferably arranged in the front plane of or outside the metal tube. Another embodiment of the device is made of a medical sample excision spoon wherein two arm parts of the spoon constitute the electrodes, both being fixed to an insulating material and provided with terminals that are coupled to the ammeter.
