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.
There is plenty of research showing the link between pH and cancer. Cancer thrives in an acidic environment, and doesn't survive in an normal, more alkaline environment. Cancer cells make your body even more acidic as they produce lactic acid. So if you have cancer, your pH levels are low and your body is too acidic.
