A mammography apparatus includes: a compression plate that compresses a breast； a moving unit that moves the compression plate in a compression direction in which the breast is compressed and a decompression direction in which the breast is decompressed； a radiation source that emits radiation； and a control unit that controls the moving unit such that the compression plate is moved to a first position in the compression direction, is moved to a second position where the position of the compression plate is changed from the first position by a predetermined variation or more in the decompression direction, and is stopped and performs control such that the radiation is emitted from the radiation source to the breast.
