Cells become cancerous when they stop using oxygen to make energy and use an oxygen free fermentation process for fuel instead. At the same time, the nagalase enzyme is released at a proportional amount to “drug” the macrophage portion of the immune system. In a healthy body, macrophages search out dying, diseased or injured cells in the body and they consume them! By “coating” themselves and disabling the immune system, cancer cells go unchecked and multiply. This test tells us whether and how much nagalase enzyme is in circulation which lets us know if there is cancer activity in the body.
