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.
The grade of the cancer refers to the appearance of the cells in the tumor and gives an idea of how aggressive the cancer is. Grade 1 cancers are made up mostly of normal-looking cells; grade 2 cancers have more abnormal-looking cells; and grade 3 cancer cells have a higher percentage of abnormal-looking cells.
