An improvement of our previous computer algorithm of cancerrecognition of ultrasound images is developed. In order for cancer tosurvive it develops its own blood supply system, which is different thanthe supply system of normal tissue. The velocity of the blood flowingthrough the cancerous blood vessels is different than the velocity ofthe blood flowing through blood vessels of normal tissue. Due to thisfact, the ultrasound signal is absorbed differently in the cancerousareas than in the normal tissue areas. The energy of the signal, thecontinuity of the signal, autocorrelation function, and frequency domainproperties are different in the normal tissue than in cancerous tissue.All these indicators are used for classifying the image of the tissue asbeing cancerous or non cancerous
