Abstract
Abstract A method, apparatus and a lifelike model of a human female breast form a breast cancer detection training system. The model closely simulates the feeding of the different tissues of the human breast and except for a tumor-free comparison model, contains at least one simulated tumor. When used in conjunction with the electronic training apparatus, the model also contains a pressure sensing means. The apparatus and method compare signals initiated by the trainee with stored signals representative of the number of simulated tumors in the model, their location, and the pressure required to feel them and provide feedback information to the trainee so as to improve the trainee's examination technique.
