The importance of this research is to study the visibility of eliminating chemotherapy as an option to treat cancer patients after removing cancerous tissue or tumors. It is proposed that laser ablation of tissue can be a very sophisticated method of removing tumors and cancerous cells from skin and internal organs such as the liver and kidneys without the need for postsurgical chemotherapy, as compared to the traditional surgical procedures which result in many complications due to the dependence on chemotherapy after each procedure for long periods of time. The carbon dioxide laser provides the cells with enough energy to be ablated one by one without cutting through the cell itself leaving behind a remnants of the cancerous cell, which has to be eliminated after the surgery by chemotherapy. Carbon Dioxide laser with 9.6 micron wavelength and 200 mW to 800 mW was used for ablating three different cow tissues, which were liver, kidney and heart. The different tissues are used as markers for the content of the water/blood percentage in different tissues in the body. This first step is necessary to determine the minimum and optimum laser power needed for ablations. Extensive power will lead to a different process which will harden the surface tissue beyond the point of elasticity of separation of the cells and then the process will fail. This paper will discuss the preliminary data of the ablation technique, using a real time camera to monitor the process, and measure the size of the creator to establish a graphical model for ablated image for each type of tissue. Future directions will be discussed as well.
