An anatomical rag-type doll is provided with a hollow abdomen accessible by means of hook-and-loop type material, such as VELCRO.TM.. The doll also has a pair of stuffed, simulated breasts. One of the breasts, representing a diseased breast, is hollow and has a removable nipple attached to the breast with hook-and-loop type material. Stuffing in the hollow diseased breast is removable, representing the removal of diseased fat and tissue during a mastectomy. The hollow abdomen is stuffed with simulated abdominal muscle and fat, as well as other simulated human organs. The simulated abdominal muscle and fat can be repositioned in the doll, as well as placed in the diseased breast to demonstrate the pedicle tram and free tram flap medical procedures.
