Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling.
A healthy cell has a pH of 7.35 while a cancer cell is more acidic. Cesium when taken orally will raise the pH of cancer cells, but not that of normal cells. When the pH of a cancer cell goes above 7.5 it dies and if it goes above 8.0 it will die in a matter of hours.
Enhance the immune system to fight the uncontrolled growth of cancer cells. Make cancer cells more vulnerable to destruction by the immune system. Change the growth patterns of cancer cells so that they are more like normal cells, and are less likely to spread.
