breast and chest share a recorded sense, so the question is not what they mean but which one fits. breast means “the front of the trunk from the neck to the abdomen”. chest means “the part of the human torso between the neck and the diaphragm or the corresponding part in other vertebrates”. chest is the more common of the two in everyday English.
