Cells ultimately lose their polarity and begin to "magnetize" to other cells, causing cancerous cell clusters. These clusters attract more negatively charged cells and spreading occurs. Most people have cancerous cell clusters but acceleration of clusters varies throughout. Additionally, the location of cancerous cell clusters may not acutely affect your body’s ability to function correctly. Poor acidic pH among other variables aid in cells losing their polarity and acceleration.

Your psychological state is mostly cumulative. So a body consumed with negatively charged cellular masses will need to proportionally increase actions to re-polarize the majority of cell function.
Chemo aids in none of this process.
Your success from chemo therapy is likely similar to winning bingo at your local Kiwanis. The overall character of your cellular production was most likely the determining factor in your survival, not a synthetic bio molecular compound which “tricks” your immune and biological response systems into a fix.
