1% of all Gastrointestinal (GI) tumors and its incidence is approximately 10 - 20 per million people per year. (scirp.org)

If the danger is not resolved and the immune battles must rage on, the mitochondria begin the complicated process of reallocating resources until the battle is won or the decision is made to institute what can only be described as suicide - cell death. (hormonesmatter.com)
But when cell death occurs from mitochondrial injury , it is messy, and evokes even broader immune responses, setting a cascade in motion that is difficult to arrest. (hormonesmatter.com)
Indeed, when we consider the trillions of microbes - clear non-self entities - that live inside and upon us, the idea that the immune system evolved simply to kill the non selves seems laughable. (hormonesmatter.com)
We can ask questions like: what resources are missing that would allow the immune army to fend off the danger once and for all or what could heal the damaged cells, scavenge toxicants and oxidants or re-calibrate mitochondrial energy production? (hormonesmatter.com)
