1. An apparatus for lesion detection, the apparatus comprising a processor configured to: detect lesion candidates from a medical image; detect anatomical objects from the medical image by extracting at least one feature map from the medical image and comparing the at least one feature map to at least one pre-stored feature map; verify each of the lesion candidates based on anatomical context information comprising first information regarding a location relationship between each of the lesion candidates and the anatomical objects and second information regarding a probability distribution of a lesion for each of locations of the medical image, the probability distribution being obtained from a learning data established prior to detecting the lesion candidates; and determine at least one true positive lesion by removing one or more false positive lesion candidate from among the detected lesion candidates based on a verification result of the lesion candidate verifier.
