1. An apparatus displaying a volume of a tumor mass destroyed, the apparatus comprising:
- means for measuring a temperature of at least part of the tumor mass;
means for measuring at least a temperature at one point in proximity of the tumor mass; and
means for providing a graphical representation of the volume of the tumor mass destroyed based at least in part upon measuring temperature of at least part of the tumor mass and at least one point in proximity of the tumor mass.

Abstract
An apparatus and method for determining a volume of tumor mass destroyed. The present invention includes a temperature probe and a laser probe having a temperature sensor. The laser probe and temperature probe are inserted to measure a temperature of the tumor mass and a temperature of tissue mass surrounding the tumor mass. By determining the volume of tumor mass destroyed, a graphical representation of the volume of tumor mass destroyed is provided whereby real-time visual monitoring of the destruction of the tumor mass is achieved.
