In the original article it says 'the human body has... cancer fighting cell ... the mitochondria'.
These caps aren't aimed at the OP, but the article author: MITOCHONDRIA ARE NOT CELLS. They are contained WITHIN a cell and all they do is give the cell the energy to do what it needs to do. They never have been cells and cannot survive outside of a cell. They do nothing more than process oxygen in order to provide energy. It's how we breathe, move, eat, sleep and do anything. They are basically the cell battery.
This article is kinda bull. Cancer is our own cells, nothing more and nothing less. It doesn't matter which cells actually divide out of control and make us ill; it could be anything. It's not an illness, it's a biological flaw within the people that get it, and it causes illness. All it is in layman terms is your cells dividing, but getting it wrong.
This article actually reminds me of those stupid articles that claim eating healthily and drinking so much water a day can cure or prevent a type of Cancer.
Rant over.
