A cancer identifying device comprising: a photoreceptor cell array comprising a plurality of photoreceptor cells (202a-202l) and configured to receive gamma photons emitted from cancer cells present in an organism; means for converting the gamma photons into a plurality of electrical signals; an analog to digital converter for converting the plurality of electrical signals into a plurality of digital signals; an oscillator for converting the plurality of digital signals to the plurality of oscillating waves; a processor communicatively coupled to the photoreceptor cell array; and a memory communicatively coupled to the processor and having processor instructions stored thereon, which on execution by the processor, cause the processor to: create a contour plot of a function of the positive and negative peaks of each of the plurality of oscillating waves, wherein the function comprises a predetermined function of one or more parameters which include: the positive peak value of the oscillating wave, the negative peak value of the oscillating wave, the distance covered by the gamma photon associated with the oscillating wave to reach the photoreceptor cell array and the time taken by the gamma photon to be detected by the photoreceptor array, wherein the instructions, on execution, cause the processor to create the contour plot on a millimeter graph comprising a positive-positive quadrant, wherein positive peaks of at least one of the plurality of oscillating waves are plotted in an upper plane of the positive-positive quadrant and negative peaks of at least one of the plurality of oscillating waves are plotted in a lower plane of the positive-positive quadrant; and compare a pattern of the contour plot with a plurality of training contour plots to identify a type of cancer affecting at least one body part of the organism, wherein each of the plurality of training contour plots are tagged with an associated type of cancer. a photoreceptor cell array comprising a plurality of photoreceptor cells (202a-202l) and configured to receive gamma photons emitted from cancer cells present in an organism;
