Method for detecting lesion and computer-readable recording medium storing lesion detection program

A non-transitory computer-readable recording medium storing a program for detecting a lesion, the program causing a computer to perform processing comprising,

• calculating, by using a first lesion detection process configured to detect a specific lesion region from three-dimensional volume data generated based on a plurality of tomographic images obtained by imaging an inside of a human body, a probability of being the specific lesion region for each of unit image areas included in each of the plurality of tomographic images;
• and
• executing, based on one tomographic image of the plurality of tomographic images and the probability calculated for each of the unit image areas included in the one tomographic image, a second lesion detection process configured to detect the specific lesion region from the one tomographic image.
