This invention provides a mechanism for making a doctor surely follow correct procedures in which the doctor confirms diagnosis information obtained by computer processing after he or she has completed interpretation. A medical diagnosis support apparatus executes diagnosis processing for acquiring medical diagnosis information from an image to be interpreted by computer processing. The medical diagnosis support apparatus accepts interpretation information as an interpretation result of the image to be interpreted, which information is input by, for example, a doctor. The medical diagnosis support apparatus calculates a degree of matching between the diagnosis information and interpretation information, and permits to present the diagnosis information acquired by the diagnosis processing when the calculated degree of matching exceeds a predetermined threshold.
