1. An information processing apparatus comprising: lesion progress rate recognition circuitry configured to perform prescribed image recognition processing on a plurality of entered medical images, thereby recognizing a lesion progress rate that represents a rate of progress of a disease-induced change in a living body, and calculate a score of the lesion progress rate as a function of (i) a number of pixels representing tissues in the medical images, (ii) a first product of a first score for normal tissues and normal confidence factors, (iii) a second product of a second score for benign tissues and benign confidence factors, and (iv) a third product of a third score for malignant tissues and malignant confidence factors; and presentation control circuitry configured to cause a presentation circuitry to present the medical images according to the recognized lesion progress rate.
