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.
Obesity leads to the reduction of SHBG (sex hormone binding globulin) a protein that binds estrogen levels and keeps them out of circulation. When these levels go down, estrogen levels go up, become active, and thus stimulate the growth of breast cancer cells. Over one hundred studies have investigated the links between obesity and breast cancer.
