1. A patient-specific device for guiding resection of a tumor located in a breast of a patient, comprising:
a locator form having a locator-form surface matching a surface of the breast of the patient near the tumor's location when the breast is imaged in a supine preoperative position, such that the locator form, when fit to the surface of the breast, restores the breast to the supine preoperative position; and
a surgical guidance cue integrally formed with the locator form and based on images including only preoperative images of the breast in the supine preoperative position, to indicate a spatial property of the tumor in the supine preoperative position.
