1. A method of detecting cancerous tissue, comprising the steps of:

  • a) recording a plurality of infrared images of a predetermined area of skin;

    b) converting each of the plurality of infrared images into corresponding thermal images;

    c) subdividing the predetermined area of skin into a plurality of subareas;

    d) calculating an average temperature value for the plurality of thermal images of a selected one of the subareas, wherein the average temperature value for the selected subarea constitutes a time series for that subarea;

    e) repeating the procedure of steps a) to d) on the remaining subareas of the predetermined area of the skin; and

    f) analyzing the average temperature value of the time series of each of the subareas, wherein when a spatial distribution of the average temperature value of a cluster comprising at least six congruent subareas is less than about 20% or more than 100% of the average temperature of the plurality of subareas, that cluster is determined to be cancerous.
