The real cause of cancer has never been known! Whether the cancer is in the form of a tumor or a single cell, whether it is a sarcoma or carcinoma, whether it is “a scarce variety” or the most common, each one starts in the same place, one small region in the brain. This information will make cancer much easier to prevent, to stop, and to cure. All cancers become malignant along a chain of events. The chain is always the same, except for details. The organ chosen is just a detail. The cause of all malignancies is a common parasite, the human intestinal fluke. Its scientific name is Fasciolopsis buski. But it does not act alone. It acts together with 4 or more partners. The first two are polonium and cerium. These are a radioactive element and a lanthanide element. We will learn more about them soon. The participation of the fluke was first described in a book published in 1993. Each is essential to make a cancer and to keep it growing. A fluke is very much like a leech. The adult sticks to one spot where it produces many thousands of eggs inside our bodies. Their attachment causes chronic minor bleeding, which later leads to anemia and pain.
