A medical image processing apparatus to accurately identify malignant transformations of probable tumors. The medical image processing apparatus including a specifying mechanism and first, second, and third computing mechanisms. The specifying mechanism specifies a probable tumor from medical image data upon receiving the medical image data obtained by imaging a subject by a single medical imaging apparatus. The first computing mechanism calculates morphological information indicating morphological characteristics of a specified probable disease based on this medical image data. The second computing mechanism calculates functional information of the specified probable disease based on this medical image data. The third computing mechanism calculates amount of progress characteristics indicating the extent of the probable disease based on the morphological information and functional information.
