Cancer : Ancient Indian Scripture perspective. Cancer isn't actually a disease, but in fact an age old survival mechanism of the body which is activated via epigenetic changes in its micro-environment or terrain of the body. When the pH of the blood begins to drop from its normal level of 7.4 to around 5.0 (from the over consumption of processed, non-organic, acidic food, GMO food), the cells of the body begin to alter their state.
